I have three screens on my desk: two for my main G5 and one for "the other computer", which alternates between a windows box and a Mac Mini (recently upgraded to a Mac Mini with an Intel Core Duo). I sometimes try to mouse across all three screens, and of course realize "that's silly" after a few seconds. Two different computers, can't mouse across 'em, right?
Not anymore. I was reading an interesting article on apple.com that referenced iCluster, a visualization project from the Scripps Institution of Oceanography that uses a 12-screen grid of 30" Apple Cinema Displays controlled by six G5s. They can drive it all from one mouse and keyboard.
How? A gorgeous little multi-platform open source project called Synergy. Not to be confused with Wincent Colaiuta's fine little iTunes support app of the same name (which I purchased and have written about elsewhere), Synergy allows you to run multiple computers with one keyboard and mouse. It's not a full software KVM (yet), just a KM solution, but it's exactly what I'd been looking for without even knowing it.
There's still a couple of bugs under MacOS X, but it's way cool. Check it out if you are a multi-screen, multi-box user. Supports X, Windows, and MacOS X.
