The stock line render was created in an awesome fractal generator called Apophysis, available here [link]
Editing in Photoshop CS5
Was just kinda messing with the program, trying some stuffs... ended up with this
I think it looks pretty cool, currently using it as my background.
The render wasn't created at a full resolution 'cos I was just messing around, now I wish it was at a higher res
Due to the randomness of the generator I can't get it generate one close to this again... for now
