Ok, so I've been on the horn with a few folks (horn being IRC / Chat / SMS) and trying to describe what I have in mind for my tattoo.
I love fractals. I adore Escher style tessellations, and I think the Geiger like 'organic metal' look would bind the two nicely.
For the tessellations, I'd love to integrate some shooty stuff. Maybe 1911s / Glocks / or ammo. I know how to do a basic tessellation (great information on the process can be found here), but the fractal thing where they go off into infinity has me a little perplexed. The binary decomposition fractal above gives a good representation of the grid I'd need to use, so once I get the concept of a non-fixed size grid, I should be able to merge the two together.
This will cover my entire shoulder and come down 5" or so down my arm. A t-shirt sleeve should cover it.
Working on some rough sketches that I hope I can give to a few tattoo artists and get something that will work.
