[S]imply from an engineering standpoint, I think this is by far and away the best [LBP level] yet. A user created a real-time working calculator that accurately adds and subtracts numbers. The level is said to use 610 magnetic swtiches, 500 wires, and 430 pistons. I didn't see what the big deal was until the camera panned up. That's when my mouth hit the floor.
