I am just throwing this out there and I do not know if it will even work....glow in the dark paint (can be bought at craft/art stores) Then wrap your bike in clear plastic wrap and paint some funky designs on it? I dunno. I like the idea about glow sticks the best though. That is probably the easiest too.
Also, there are CatEye Orbit Spoke Lights (sold at REI and other places I am sure). They clip onto your spokes and light up! I think they are pretty cool.
Good luck!
