I shared this with some of you a few years ago, but it keeps coming up in conversation, so I figured I might as well post it again. It really is an awesome piece of technology. A window with which you can use gestures to affect what is displayed on the window. Thoughts on how this works? Is it merely a projector shining through a window? Is the window actually creating semi-opaque images that create shadows on the floor? More likely the first, but still a neat idea. Imagine though, if it actually could create semi-opaque pre-programmed images. We would be able to have patterns in lekos with life-like animated movement.
