One of my students told me about this today, and I have to say, I'm impressed. This guy has about 25 different time lapse edits he's done. He's VERY talented when it comes to compositing and editing. This was one of my favorites. It's seven minutes long, but took over 4hrs of real time work and 244 layers.
That was just simply "WOW!" I teach IT and have yet to see someone produce that sort of quality with photoshop.
