I've ended up in this page today, it's too funny :P It has cats, lols and electronics :)
Basically, a guy built a system that detect when the cat jump in the kitchen table, and scares the hell out of him with a combo of blender noise and strobo lights :P
The short clips are delicious (the last one expecially, made me ROTFL), and there are also details on the implementation!
