There's probably nothing worse than spilling liquid on your Mac. But what happens if there's liquid inside your Mac?
That's what LiquidMac attempts to do as it uses any Mac equipped with a sudden motion sensor to simulate liquid sloshing around inside your Mac when you move it. There's not much point to it other than to have a good old slosh around and impress your friends. You can tilt it from side to side and get the genuine effect that there's liquid inside.
In reality, you might notice that it's not quite as sensitive as it should be. You have to shake, rather than tilt your machine and even then the results are not great. In the end, the liquid might move either too slow or too fast or not react at all to tilting.
As far as gimmicks for the Mac go, LiquidMac is a surefire way to end up throwing your mac around so much it ends up breaking - use with extreme caution.
