I could swear I already blogged about this but I must be going crazy. Anyway, Prism allows you to run any website as a standalone app. As I have already mentioned, I love GrooveShark (a Pandora-like internet radio, but better). With Prism, I can run Grooveshark in its own window and launch it right from my Start Menu, Desktop or Quick Launch Bar. Slick. So check it out. Prism.
