Here is a really cool short from Tao Tajima featuring footage from the streets around his Tokyo home. In Night Stroll, discovered on SHFT.com, we see geometric shapes made of light interspersed throughout the darkened streets of suburban Tokyo. The animated shapes were created (we think) by tracking the footage with 3D computer graphics software before adding CG shapes and reflection. However he pulled it off, it looks amazing.
