Bitfall is a waterfall that displays images by changing the sizes of the water drops it drops. They are currently having a huge boost of traffic, which their internet host didn't much like, due to curious onlookers like myself so the images and german descriptions can be found here right now, but the ubercool Quicktime videos are offline at the moment.
Still, this is so neat I wonder when it'll be used as actual ad 'water' posters to sell us Perrier. ;)
File under very cool.
