Psplcd with lolcat

Today I've managed to finish up the hard part, building the VHDL code to interface to the SDRAM chip & act as a dumb framebuffer - It's a little slow at the moment but works very well.

Wasn't so sure it was going to go smoothly as I had some fun corruption issues earlier, but that turned out to be that I had accidentally reversed some address pins in the FPGA pinout.

This design is currently occupying 16% of the slices on the Spartan-6 FPGA - plenty of room for future experimentation!
