Merqury - great job on the rings...
I did a /fail attempt but i'll upload anyways.
For some reason I thought it would be a good idea to use a Quake ring for the rings but the dam nail is too long.. but i did it anyways 
Also changed the particles to the NIN logo. Here for anyones amusment.
Heres a tip:
Open the original ring in Photoshop. Using the circle shape tool, trace a circle over the ring, so it exactly matches the inside of the original ring (Hit Ctrl+R to bring up the rulers, and drag blue marker lines down to match the top and left tangents of the circle to make it easier). Rasterize the shape layer, then in blending options, apply an inside stroke of any color, only make the size huge as to fill the circle itself, then set opacity to 0 to render the circle transparent. Then, apply a drop shadow, reduce the distance to 0, and set opacity to 100, so you get a black shadow ring. Erase the original ring below. Use that shadow ring as a base for all your tunnels, so you understand the bounds of the track and such. Then copy your quake ring over it, and fit the left and right extremities to the shadow ring.
Darchinist: GREAT stuff. I'm saving it.
