Fire Screensaver lets you start fires on your Mac desktop!
If you’re looking for a cool fire screensaver for your Mac look no further. Aurora Screensaver allows you to start fires all over your Mac desktop by the use of your multitouch trackpad! Each finger burns it’s own fire, it’s really quite fun to play around with. Since multitouch input is used, you just have to hit a key to exit the screensaver. This is Snow Leopard only and requires a trackpad.
I found this digging around on Apple.com and am quite pleased with my new ability to have a fire on my Mac desktop! Surprisingly entertaining!
