Something similar I seen on this site I believe is was located in Russia, but it was also on the side of a building, I did a search and I can seem to find it. Maybe someone else will have better luck then me?
I believe this is the video you are talking about. I couldn't find it here, but with a little searching (not much really) on YouTube, it came up right away. Here it is:

Pretty neat stuff. So, if they can do all this, then why can't they fake an alien invasion, or religious experience, or spirals, etc.?
