"File this under “wish we had this when we were kids”: LEGO is starting a new program called LEGO Factory where you can download a desktop application that allows you to create a custom brick design. You can take the designs you create using the LEGO Digital Designer software, upload them to the LEGO website, and actually order a kit of LEGO bricks that will make the design you spec’d out. Sweeeeet! We really ought to finish this post but, um, we got some LEGOin’ to take care of — see ya!"
