Here is a project we made for an AR course we had. Often you want to be able to have some big screens you can interact with. This explores the possibility of using relatively cheap technology to get a surface with multiple touch support. The idea is to use one (or more) RGB cameras to detect where the screen is occluded. This uses Unity and some GPU programming to get the wanted real-time performance.
Quick! Quick! Get the packages before the customers get too mad! Oh, you can’t find it? Well, I hope you can if you look again. This is actually one of my favorites that I’ve made from Ludum Dare. I just think it came really great together.

The game even has upgrades for the car, lots of different missions, and a local high-score system for each of the missions.
