Virtual Sandbox

I am always on the look out for that uber cool mix of technology and art, form and function online. I have Guy Kawasaki to thank for bringing this gem to my attention via a recent tweet...

The website is called http://thisissand.com and it is a virtual sandbox. A bunch of clever folk got together to create a place to play online. You create with sand. Add color and design as you wish. Play to your hearts content. And best of all... no clean up. Read their more about the project on the This is Sand blog here or take a look at the Sandbox Gallery here.
