I heard about Balsamiq recently and figured I’d pass it along.  It’s a nice tool for quickly creating screen mockups.  After playing with it for about 5-10 minutes this morning, I’ve got to say that I’m impressed.  I definitely think it is a nice alternative to using powerpoint.  It is an Adobe AIR application which means that it’ll run on mac, windows, or linux.  They even allow you to test it out online, at their website.  Check it out!
