There are several brands out there who offer them however I don't recall the names off the top of my head. I know Paul Frank offers one like that, not sure if Paul Smith (made by OP) offers one. If you have time this weekend, visit the folks at Bruce Eyewear. They are a small store and the staff have been very helpful. Nada, Paul and Elaine all know their products.

Your other option is to pay a visit to Eyes On Twelfth, however, I was snubbed by them one two occassions and decided to take my business elsewhere.
