Well, not...I saw a 4-D movie way back in the 1980s. Well, not quite the kind of 4-D you're talking about. It was called "The Hypercube" and it depicted a 4-dimensional cube (aka hypercube, or tesseract) rotating in hyperspace, as projected into 3-D space, and then of course flattened to 2-D for the film. We can see the 3-dimensionality of objects rotating on a 2-D plane, but our brains cannot wrap themselves around the 4th geometric dimension, except by analogy. I've tried in vain to find that exact same film online, but these ones come pretty close:<br /><a href="http://www.youtube.com/watch?v=iXYXuHVTS_k" rel="nofollow">Hypercube 3D Computer Animation</a><br /><br /><a href="http://vimeo.com/1076061" rel="nofollow">4d-Hypercube</a><br /><br /><a href="http://www.youtube.com/watch?v=-x4P65EKjt0" rel="nofollow">Hypercubes, starting from dimension 0 up to dimension 6!</a><br /><br />This one has further explanation:<br /><a href="http://www.youtube.com/watch?v=9DoSqeJNG74" rel="nofollow">Hypercube Demonstration</a>Rosie Pererahttps://www.blogger.com/profile/09554035581795923555noreply@blogger.com
