27173 Icon 16 x 16

I'm looking for a 16 x 16 icon that will be next to the address of my site. I have no clue what I want it to look like so I was hoping people might want to show some samples, watermark them and let me chose? I don't know if that's a possibility. My site is a download site. People pay money to join and then have access to all my downloads. Whatever the icon is it needs to have the letters OPD in that order. I don't care if they are interwoven together in some cute way. I don't know if this is possible, but if you'd like to try your hand at it, I'd appreciate it.
