Tile Machine.

One of the things that I love about the Internet is that there’s never a shortage of goofy stuff you can do to waste time. That may sound like a stupid statement, but that’s because it is. Using the Internet for worthwhile purposes is great, but when you feel like you can’t do anymore serious research, there are plenty of games, animations, and tools to waste your brain cells away with. You may as well create something while you’re having fun, and you can do that very thing with Tile Machine.

This site gives you a Shockwave drawing pad to mess around with. All of your regular drawing tools are available here, and a palette of colors awaits you. Create and edit as much as you like, and view your masterpiece in a variety of sizes. Once you’re done, you can save your tile for personal use (as a wallpaper, etc.), send it to friends, or submit it to the gallery.
