I just wanted to share this great application for you mac users out there who may be interested in doing something similar to what Rainmeter does on the Windows platform.

Don't worry about the fact that you probably don't know the code necessary to make anything yourself, because there's an awesome website that has pretty much everything you could possibly need to get started.
