Here you can create your own colorful digital lightbeam. You can control its brightness and select the color across the entire spectrum. It will not only impress the kiddies but also be great for rock concerts, dance parties or useful for lighting up rooms.

It is free but you still need to have iTunes installed in order to open the link, and you must have an active iTunes account to download the application.
