by Have a look here at this site. It's a freeware JAVA app that will run on PC and Mac. It's a gameboard (whiteboard) for displaying interactive online maps between connected users. Very useful for visual descriptions when gaming via Skype or IM. I know that there are others out there, but this is the first one that seriously loaded on my Mac without having me install a bunch of other stuff just to get it to run. It looks good tool. There's a few other tools there as well. A character creator and dice tools.
Worth a look!
