LEGO lovers look!
There is a Lego nerd inside all of us, except for me. I can see the pain in your eyes from the memory of a small boy protecting his prized Lego masterpieces from your brothers/sisters/minions of Satan. Anyways there is a program called Ldraw, a CAD with every Lego piece you can imagine. No longer do you have to keep trash barrels of Lego pieces in your basement. Its an easy typical CAD program, just drag the pieces into one of the four views and let your blockhead run wild. I would recommend at leased scanning through the website for details before downloading.
