Lego Digital Designer

This is way too cool. I got this from the lifehacker blog entry about it, which has a link in it, but you can go directly to the link here if you would rather do that.

This program lets you play with virtual Lego blocks to design the ultimate Lego masterpiece. When you're done, it lets you order all the pieces you just used as a special kit!

There are starter models to work off of, and there are 763 available block types! This could be good just to get the pieces from the sets I have that aren't complete anymore - but I could make them more awesome now! . . . for the kids I mean! . . . yeah . . .
