Finally, have you check out online sand art at http://thisissand.com/? When you click on it you'll think the page didn't load because it comes up all grey except for a small square in the upper left corner. But press your mouse down and sand will start to pour out of the arrow. Click on the little square in the corner for the very basic instructions as well as a link to the amazing gallery. Have fun playing with colors and design!
