One blog that I have in my RSS Feed is CoolTools by Kevin Kelly. I always see something cool every week that I could apply to riding. One is super reflective tape:

If you have no reflective material on your gear, you could try using this (which seems stronger than what you can buy at places like Cycle Gear) and cutting out some unique shapes. I may try doing this to add some small reflective symbols to the bottom of my new jacket.
