It's a dream come true for millions of children and Pixar fans: Michael McMaster and his resourceful friends have built a life-sized, moving, and talking replica of Wall-E. As part of YouTube's Geek Week, Tested visited McMaster's workshop for an up close look at the mesmerizing robot, which was meticulously pieced together over the course of several years. Using a Yahoo Group to keep in touch, McMaster and his builders club pals had already assembled an equally impressive R2-D2 robot. So after hearing about Wall-E's impending release in 2007, making a real-life version of Pixar's new character seemed like the natural choice.Nailing the exact scale of a CG character proved challenging, with McMaster's team turning to known objects like VCR tapes and a Rubix cube to work out the size of Wall-E's "hands" and working on from there. "Blu-ray was our friend," he said of the hi-def format, which provided detailed screen grabs that helped the group replicate every inch of the lovable character. Stay tuned.
