looks like i get first attack since you're computer is going slow with the image planes

ok, this is just a bunch of polys, 1052 tris already...
21 cylinders of subdivision 10, and 6 cubes, three with extrusions

as you can tell the flat cube/platform thing is rather confused and needs some cutting up before it gets its shape
