I am probably repeating a bunch of stuff that has already been said. Anyway, magnets can be arranged in some interesting ways. I've seen a few devices spin for a suprising amount of time. However, I think the moment you put a load on the device it spirals down and quits even sooner. However, this is not to say one can not arrange magnets to produce a useful engine. (with very little input, in order to get massive output)
One way I look at perpetual motion is this. Take a wheel, and spin it very quickly and put it in orbit around the earth. The wheel will spin for a very long time, but that is only because it isnt doing any work. If we tried to use the wheel for energy, the wheel would slow down as we essently suck energy out of it.
So even if perpetual motion relatively exists, when you put it to use, it stops.
