When you were younger, did you ever make sand art bottles? You know, you fill a bottle with layers of different colors of sand. You might fill the bottle at an angle to create a zig zag pattern, or you might poke the sand down on the sides with a small stick to create some great waves.
Now you can make the same great art online and with the mess or hassle! With this sand art, you choose your colors and drop them in where you want them. You can even remove sand if it gets where you don't want it. Okay, so it's not exactly putting the sand in a bottle, and it looks more like colored pixel sand in an ant farm, but it's fun, relaxing, AND you can save it when you're done!
