While the early mornings are still dark thought I'd mention this product I got a couple of cans of for Christmas, Volvo Life Paint:

Pretty neat stuff, spray it on and it glows brightly under headlights. You can get it at the Volvo dealership here in town (Valentine Volvo), not sure what the retail is.
My commute only has a bit of road riding (8th avenue from 1st Street NW eastbound to Nose Creek), but I figure any extra stuff to be more visible to cars can't hurt. I know some of the more hardcore bike folks around town hate stuff like this, as in their opinion it shifts responsibility fully to the cyclist instead of the drivers.
