There was a horse racing game around when I was a kid, and it involved a long
felt strip about 8' x 2' with the lanes marked on it. The felt was pulled tight
and anchored at one end, and at the other it was fed into a mangle like device,
so the felt was taught up having a slight downhill incline.
The idea was you all placed your horses at the start, and some elected person (I
can't remember how or who got selected to do this) turned the handle on the
mangle like thing, that had little bumps on the rollers - this made the cloth
vibrate, amnd the horse all started to move forward.
It was so random, that never did the same horse win, and no matter how fast/slow
the 'turner' wound the handle there was no way to influence any horse at all.
It's a real shame you don't see games like this any more.

Have a look at industrial vibratory feeders. They're usually a large metal bowl
and track connected to electric vibrators. They're used to feed screws, pins,
bearings, and all sorts of small parts. Just about any small part can be fed,
and there's nothing special about the parts (other than that they need to be
hard).
The parts will go up a spiral ramp around the inside of the bowl, and then down
a track to the feed escapement. They do this strictly under the influence of
vibration. I really have no idea why they go up the spiral ramp, but they do. [ Reply to This | Parent | # ]
