It looks very cool! What's the GPU & CPU written in out of interest, I think I saw on your twitter you've written something to translate to verilog, is that used for this?
I suppose your target audience is mainly more familiar with verilog (though not necessarily I suppose - could have only ever used VHDL) but I'm interested in playing with it, just haven't used verilog, or FPGAs at all, since university.
Then look at the "output" subdirectory and you'll find a verilog generated file for each example of the parent directory.
