FPGA's rule themselves out. You can use them for prototyping your ASIC, but FPGA's are extremely costly per silicon area, and generally less power efficient than anything else. Oh, and nobody is using triangles because hashing lends itself so well to Proof-of-Work. The "work" must be difficult to perform, but very easy to verify. Like a zip file that takes 20 minutes to compress, but only 5 seconds to unzip. To verify a triangle you would have to re-render it.
