*******www.fertur-travel****/cusco_to...Pisac is famous for its arts, craft and food market that takes over the town, and for the ruins of a fortress that stands on a high ridge nearby. It marks the starting point of the Sacred Valley of the Incas.Driving in from Cusco, you can see the white awnings that spread all over town for Market Day, every Tuesday, Thursday and Sunday.Avenues and paths are draped in tapestries, pottery and artwork. As you get to the main square theyre replaced by a cornucopia of potatoes, corn, fruit and vegetables, all sold by women in traditional dress, along with stalls selling kitchen implements, and a rainbow selection of dyes and pigments.A short drive takes you to the top of the ridge, and the ruins of Inca Pisac, broken into four sections, each linked by a narrow path that hugs the ridge.The fortress and the Intihuatana or Temple of the Sun offer spectacular views of an amphitheatre-shaped valley filled with agricultural terraces. They continue high up on mountain ridges surrounding the site. The Incas dug up rich soil from the valley floor to grow huge crops of corn and quinoa at high altitudes.The ruined fortress looks across to a hillside pocked with funeral niches. The more intricate and elaborate curved stonework at the Temple of the Sun reveals the trapezoidal archways and smooth, gapless walls that are hallmarks of Inca architecture.Fertur Peru Travel.A full service travel agency and tour operator dedicated to making your journey to Peru a dream come true.Visit us at:*******www.fertur-travel****/cusco_to...trip to peruflights to peruperu flightsflight to peruTourism Peruperu airlinesPeru tours to Iquitoshotels peruperu tourhuaraz perucaraz peruinca trail perutrip perutourism perualpamayohiking perutravel agency peruclimbing perutour operator peruperu tourismtrekking Peruperu flightsperu bike tourstour companies

Today, YOU are going to draw Kobe Bryant. It doesn't matter if you have prior art training or not. This video will break the process down in to simple steps so that anyone can do it. Grab a pencil and paper and let me show you what I mean. Remember to pause the video when you need to. Here we go. Step 1: Draw an oval shape for Kobe's head. Notice that the bottom of the oval looks like an upside down trapezoid while the top of the oval shape is rounded. Step 2: Make four horizontal lines. The top line MUST intersect the midway point of the oval shape. The lowest line should be placed at the bottom of the chin. After drawing the top and bottom lines, add two EVENLY SPACED lines between the top and bottom line. At the end of step two, you should have THREE evenly spaced segments between the top and bottom lines (refer to the picture). Step 3: Observe the six dots that I added. The top four map out the corners of Kobe's eyes, while the bottom two map out the corners of his mouth. Lets look at their relationship. Notice that these dots are leaning towards the right side of the oval. This is due to the fact that Kobe's head is slightly turned. Also, take a second to notice the distance in between the two eyes is equal to one eye length. Finally, notice that the middle part of the space designated for each eye, will line up with the outer corners of the mouth. Now, draw in the six dots. Step 4: Draw in the eyes....The upper eyelid as a rainbow shape and the bottom lid is close to a straight line. Notice that the iris is partially blocked by the upper eyelid. Step 5: Encapsulate the eye in the oval shape that I just added. Step 6: In this step, make the bottom of the nose by drawing three connected, upside down arches. Do not worry about the bridge of the nose yet. After you make the bottom of the nose, draw the shape for the upper lip...... The upper lip looks like a squished McDonalds logo (picture the golden arches squished). Step 7: Add the bottom lip. It is similar to a banana shape. Notice that the bottom lip is thicker than the top lip. Now that we have the eyes and part of the mouth done, take a second to notice the perfect square that is formed when you connect the points from the middle of the eye and the corners of the mouth. Make adjustments if you do not have this perfect square. Step 8: Draw in the two shapes between the eyes and nose. Like the bottom lip, these shapes are very similar to banana shapes. They will help us shade the nose later. Step 9: Now add in the ears. Due to the fact that Kobe's head is turned; it appears that his left ear is smaller than his right. This, of course is not the case, but draw what you see. Step 10: Draw in the lines, stemming from the chin, as well as Kobe's dimple lines. Step 11: Draw in Kobe's hairline. Again, due to the turn of his head, you will see more hair on the right side. Step 12: Erase the construction lines Now, I will show you how to shade your drawing. Don't worry, this too, will be easy! You have three options to learn shading. Option one- click the link in the video description to go to a webpage that I made for this video..... on my website, merrillk****. You will see a series of 17 steps with picture references and words. You will also see a free downloadable resource that you can print. Option two is to watch a shading demonstration in the second part of this video; and option three is a separate video; where I will demonstrate how I shaded Kobe at a slower pace. Please take advantage of all of these options. I am confident that they will help. Special thanks to Rico Shen for use of his photograph via Creative Commons.

*******www.jomadeals**** TX 800 Series Titanium Linear Chronograph Dual-Time Zone Mens Watch T3C315. Your long search is over. The greatest watch ever has been found. This deal of the day is $349 with free shipping (52% off the$725 retail price). Sale ends at midnight tonight (EST). April 1, 2010 Call me Ishmael. I’ve been traveling these many months on this miserable ship with a Captain who seems to be going mad with his search. All day long, he scours the waters, looking for, what he calls, “the beast that took me hand.” Yesterday, events unfolded that will be lauded for generations to come. We found this “beast,” only to discover that it ‘twas no beast at all, but a simple, yet stunningly sleek, wristwatch. It happened nigh until noon, when the skipper spotted something off the port bow. We all rushed to see, and crashing over the waves, we saw it: the TX Series Men’s Linear Chronograph watch. It leapt through the waves like the majestic black beast that it was. Black ion plated titanium case with high grade black rubber bracelet. Unidirectional rotating titanium bezel. And a great, black dial with 'Super LumiNova' luminous hands and hour markers. We wondered how such a thing could survive the waters these many months. But we saw that it was also water resistant at 100m. Truly it was a great, astounding, magnificent creature…er…watch. When the Captain laid eyes on it, he snarled and whispered under his breath, “I have you now, black beast.” He dove headlong into the water after it. We never saw the captain again. Which was weird, because we actually caught the beast fairly easily in our nets a few minutes after spotting it. I guess with one hand, the captain just wasn’t a very good swimmer. But now that we have the magnificent beast in our possession, we are sharing its glory with the public at a 52% discount below retail value. We hope you appreciate it. Because, like the sea, if you fail to respect the TX, it will swallow you whole (or you might just lose it or something, and that’d be a waste of money. No one wants that).

*******www.fertur-travel****/cusco_tours.html Koricancha was the center of the Inca cosmos, the point from which 42 lines extend arrow-straight in all directions and sometimes for hundreds of miles out across the old Empire. Along these lines the Incas built hundreds of shrines. Koricancha is often called the Temple of the Sun, but that was just one of the buildings that makes up the complex. It’s an unusual sight, with the Convent of Santo Domingo built on top of Inca stonemasonry, but inside entire walls and rooms remain intact. These chambers were revealed when an earthquake damaged the convent in 1953, but left the Inca walls unharmed. Authorities decided to rehabilitate the site, and visitors can now walk through several of the temple’s original chambers. The dark stones, sharp edges and almost seamless stonework are the most intricate found in Peru. Trapezoidal archways and sloping walls show the Inca’s ingenious building techniques, but the curve of the outside wall, best seen from the street, is among their greatest achievements as stonemasons. The walls of this temple were once covered in pure gold plates, and implements and statues made from the precious metal filled the courtyard. Historians describe a “field” of corn, with leaves and stems of silver, and kernels made from gold. All of these objects were a central part of religious ceremonies devoted to the sun god Inti, and the creator god Viracocha, performed by hundreds of priests around the clock.. Much of the gold was taken from the temple and used as ransom by the last Inca emperor Atahualpa. The rest was melted down and shipped off to Europe by the Spanish in the early years of the conquest. Koricancha was not just a temple, it was also the Inca’s main observatory, the center of a grid of astronomical points around the city used to measure solar movements. It’s from this starting point that Cusco takes its original name Qosqo, meaning “navel of the world”. Fertur Peru Travel.

*******www.fertur-travel****/cusco_tours.html Not far from Puca Pucara, on the road from Cusco to the Sacred Valley, Tambomachay combines intricate stonework with the Inca’s devotion to water. Known as the Baths of the Incas, a number of aqueducts and channels run through the site. But the focal point is a string of carefully designed waterfalls, which split spring water into a series of cascades… …that fall in such a precise and delicate manner that it’s believed they were built as part of a water cult. The trapezoidal niches on the high terrace and off to the side of the waterfall are among the most highly crafted stone constructions left by the Incas. The precision of the falls is matched by a similar water feature at Ollantaytambo, but the Incas also showed great control over water for more practical purposes. Their use of stone irrigation channels to feed agricultural terraces around Cusco and the Sacred Valley allowed them to grow abundant crops at high altitudes, something previous Andean cultures never achieved.

*******www.fertur-travel****/cusco_tours.html Pucapucara on the road from Cusco to the Sacred Valley is often called the Red Fort. But it’s more likely it was a customs house for traders entering the imperial capital. From the valley below it presents a sheer stonewall, but from road on the other side it appears to be a more open building with few defenses. The walls include examples of the Inca’s distinctive trapezoidal niches also found at Machu Picchu. The building includes a number of rectangular structures that were most likely warehouses. It also includes channels that fed running water throughout the complex. Fertur Peru Travel. A full service travel agency and tour operator dedicated to making your journey to Peru a dream come true.
