I saw this on the Mary Sue and had to repost it. It originated from Slothfurnace.com which has all kinds of KOOL Geeky stuff. It includes how to make lightsabers and blaster and really kool backgrounds. Check them out.
Even I did not start my kids out this early. Last weekend, my 3 year old son was dueling his 11 year old sister with lightsabers and I was proud. But this makes me feel like an inferior geek dad for not starting them out earlier.
