Canon L Lens Red Ring Tattoo Only for Die Hard Enthusiasts

Flickr user Plan_9 wanted both a Canon tattoo and a wristband tattoo, so he decided to get a Canon L Lens red ring around his wrist. The next step might be to include some aperture and focal length information on his knuckles. If you decide to get a similar tattoo, you’d better be pretty set on sticking with Canon.

What would a similar tattoo for a Nikon fan be?
