Just saw these on TV. Hokey Spokes for your bike

Just saw these on TV. Looks like they make different designs when the wheels spin. Great idea for night bike riding!

Here is one of the originators of this, and you can buy a kit from her:

These are a bit more versatile and programmable.

I used to have a set (2) of hokeyspokes. They're pretty neat. I got several complements on them and they seemed to generate a lot of attention. You need at least two per wheel, though, three being even better, other wise, they'll throw your wheel off balance and you'll feel a bumping, while riding. The hokey spokes are also programmable, but only for messages. They communicate with each other, too, which synchronizes their patterns for each wheel.

I sold 'em here, on CPF, a year or two ago.

They were also mentioned in this thread a year ago: http://www.candlepowerforums.com/vb/showthread.php?t=112694

Link (for the bicycle version) at the bottom of that thread is dead now though.

I want a programmable one. Nuts n' Volts magazine has a writeup on how to make it yourself, although I don't do that kind of thing, it was cool to read.
