Drum Sequencer for Digital Logic Design Class

I this afternoon I put together the high-level design for a drum sequencer that our group will implement on a Xilinx FPGA using VHDL code.

I kind of got a bee in my bonnet that drove me to build this. Lots of soldering; coded from the ground up. I will add a little bit of the code here in the near future, as I am particularly pleased with the cleverness of the "Rain" algorithm (which is like some sort of recursive state machine I ended up coding).
