I love that style with gears and mechanical objects, so I attempted to make some gears myself in Paint Shop Pro 9, which is my favorite program. I used vector creating my own shapes of gears and such. I also used my own photos of metal, rusty things etc. I used bevel to give it a 3D Look. Every gear I saved as a tube for further use, as it was a big work to create these, so it was pitty, only to be able to use them once, right? At last I placed my gears on a rusty background and here you see the final result with shadows and such to give it a 3D look.
