This is pretty damn cool, and I know you guys will appreciate it.  

For me it was Saturday morning, dumping out my drawer of Legos and building random crap (my favorite was the plane from Tail Spin, complete with backdoor that opened and the little air disk thingy that the young bear cloud surfed on).

Well here's the digital equal to it.

It's a graphical version of my Lego drawer with all the pieces I never had.  It's free to download and pretty daunting so far.  I used to just grab what I had and make it work, but now they're all there!  Check it out, I'm going to see if i can build a silly little house and post a screen here :)
