A triple layer ring with a very phalic tube in the center, now wind a dodgy stair case up around that tube. In the bottom of the tub place a BFG with a bounce pad back up to the top. The top ring layer is completly open and surrounded by lava.
Not really a map worth d/loading if you ask me, still, you might think differently - screen shots says it all :]
