Interactive LED coffee Table??? How to???

Hey All...Just giving someone an idea for an instructable, the Interactive LED coffee table designed by Evil Mad Scientist is IMO pretty damn sweet but i can by no way afford the kits or table, so I was wondering if anyone could tell me how to go about a DIY. it looks fairly simple but i'm still learning the basics of electronics.
here is their website

even something similar would be pretty sweet.
