Anyone joined in on the Lego BuildwithChrome feature of the 50th Anniversary? It doesn't seem to be as spectacular as I had imagined, but you get to create "art" with up to 1000 (virtual) pieces, and have it "pinned to the wall" (the google map of AUS & NZ) for others to find and view.
Google Chrome is required to view 3D versions, but I think any browser can see the 2D artworks.
