DIY multitouch table explained step-by-step

Those tempted by the idea of building their own multitouch table but put off by the high degree of difficultly may want to check out the latest DIY walkthrough by "turkey tek" at the ever-useful Instructables website, which breaks things down step-by-step. Like similar setups, this one relies on a projector for the main component, but thoughtfully employs a swivel ceiling mount so you don't have to sacrifice your home theater for the cause. As for the rest of the project, while it's certainly well-explained and helpfully-illustrated, it's still quite an ambitious homebrew endeavor, so be sure you know what you're getting into before you start busting apart webcams.
