Bicycle helmets are usually ugly as sin, but I found some super cute ones a few years ago and received one as a gift.
The typical helmet: UGLY.
Nutcase Helmets: SO cute!
I have the one with the rainbow dots all over it. 3rd row down, 2nd from the left. I love mine. I was paranoid after I got hit by a drunk driver and wanted a helmet that really stood out. Be prepared to have everyone stare at you though. That gets a little annoying after a while.
