Hmmm, actually, with the low cost of optoelectronics and microprocessors, 
and the fact that most skate wheels are SPOKED, that WOULD be a way to go.  
That's my field--embedded real-time control... but I get enough of that at 
work... otherwise I could make something that clips on the toe or heel and 
shines through the wheel spokes... then you'd need an IR link to the wrist-
mounted display readout... I smell PATENT--LOL! ;')
