Control Stuff With Your Mac | Make:
Andy writes "I picked up a Velleman K8055 USB I/O card the other day and was a bit disappointed that the only software that came with it was a closed source Win32 DLL and a simple control panel for the board. So I don't have to boot into Windows to play with it I've produced a Mac OS X application that talks to the board. It's open source too so you can write your own control applications". Link.
