Forbidden Lego, a new book from No Starch Press, is a compendium of recipes for building anti-social Lego projects -- looks like good, eye-removing fun.
Forbidden LEGO introduces you to the type of free-style building that LEGO's master builders do for fun in the back room. Using LEGO bricks in combination with common household materials (from rubber bands and glue to plastic spoons and ping-pong balls) along with some very unorthodox building techniques, you'll learn to create working models that LEGO would never endorse. Try your hand at a toy gun that shoots LEGO plates, a candy catapult, a high voltage LEGO vehicle, a continuous-fire ping-pong ball launcher, and other useless but incredibly fun inventions.Link (via Geekologie)
Once you get into the spirit, you'll want to try inventing your own rule-breaking models. Forbidden Lego's authors share tips and tricks that will inspire you and help you turn your visions into reality. Nothing's against the rules in this book!
