Okay so. I plan to build a multitouch table as close as I can to Microsoft's but within the $500 budget. Some people call it impossible. I say it isn't. I'm ebaying it all the way with my parts I use. It's going to use rear DI (diffused illumination) like Surface uses. So I will keep this thread updated as the project goes on. Also right now this is what it should look like.. but bigger.
