Video game, FPGA CPU or SDR?

So I'm looking for volunteers who are interested in making something cool on the weekends.

Basically it falls down to 3 things: 1) a video game using Irrlicht or Unreal (C++), 2) an FPGA based CPU using verilog/vhdl, 3) something cool with SDR (software defined radio).

Let me know if any of those 3 things interests you, by sending me a message on the form at https://www.drudget.com.au
