So awhile back I was thinking, “You know what would be funny? A screen saver that fakes a kernel panic!”

For those of you who might never have seen one, a kernel panic is basically the most shocking crash that you can get on a Mac. It’s Apple’s equivalent to the famed Blue Screen of Death.

What a great way to play a prank on someone, or frighten yourself.







So here is the end result, a harmless screen saver that faithfully emulates the horrifying experience of a kernel panic. It comes complete with a misleading Quartz Composer Preview so that the effect is all the more terrifying.

Update: KPSaver is now 64-bit and compatible with Mac OS X 10.6 and above. Legacy users can download the old version here.
