Playing with sand

Browsing ezprezzo.com I found an insanely cool video. It's a sand animation artist who, using only her fingers, draws with sand on a glass table. I had no idea sand could look this cool in a 2-dimensional form (sand castles, being 3-dimensional doesn't count). Check out their homepage and pay special attention to the video clips.
On that same site I found an awesome Lego model of an aircraft carrier ship. Check out the detail on it. Also notice the size of the small Lego men, which means that the carrier must be huge!
