What if we could draw on buildings?

Actually, we can! with a laser!

The guys from Graffiti Research Lab came up with the idea and they called it L.A.S.E.R Tag.

For my team’s idea, one of our option is to make something interactive as well. So I was wondering, what if we could draw on to the Grand Canyon.

The only problem now is where can we get a powerful projector and how do we power it.

Anyone have other ideas?
