No Startch Press is getting ready to release another LEGO book, this time full of models and contraptions that might be a little on the fun dangerous side. Called “Forbidden LEGO,” it’s most intriguing because of its authors: Ulrik Pilegaard and Mike Dooley, both of whom worked at LEGO on the Mindstorms project. (Original, not NXT.)

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.

Just when I was about to give away my NXT set, they pull me back in.
