I have recently been reading a series of articles here and here regarding the multi-core parallel programming problem. The guy seems like he could be a little out there on the edge, but his concept for the COSA project, and fine grain parallelism seem really attractive to me. I have been thinking about trying to implement a COSA virtual machine to try it out.

I have also been thinking about trying to implement the COSA hardware in an FPGA, but that seems like a much harder project
