It *IS* the kickstarter code:
https://www.kickstarter.com/projects/725991125/open-source-graphics-processor-gpu
I have got the code from git and it contains references to 2 authors:
Frank Bruno
Jim MacLeod
That leads to here: http://www.siliconspectrum.com/exec_team.htm
Without *altera* and *sym* files, it is over 80K lines of verilog code.

I can't tell who did this latest GPU and without spending a bunch of

an actual GPU in there, or is it just memory and video controllers?
What kind of rendering can it do? The blog seems to imply that 2D
isn't even working. We could do a dumb framebuffer in 2007. There were
some people from Silicon Spectrum (that bought the IP from Number Nine)
who were looking at putting their design into the open source, and I
think they did a kickstarter. But I can't easily find any info on the
identity of the people who are doing this one.
Sometimes I worry that the OGP may have inadvertently caused some
trouble, because every time someone else tries to do the open source GPU
thing, the response from the community is "been there, didn't do it."
If we had a synthesizable design in Verilog that COULD perform at
cutting edge performance, if only we could put it in a cutting edge chip
technology, then that might help. I have bits and pieces, but I haven't
had time to work on it.
Currently, we've got a paper written that we're submitting for
publication. It involves an open source GPU developed by another member
of OGML. And we're looking at doing some other research in that area.
Once we have a few papers, we can apply for grants. We did try to get
one masters student to work on OGA2's ALU, but that didn't work out very
well. If we can get funding, then we can justify spending a lot more
time on it ourselves, along with funding students. There's lots of room
for research on GPUs, and one or more completed synthesizable GPUs will
emerge as byproducts. Currently, we have a graduate student collecting
the latest research on GPU memory systems (virtual memory, exceptions,
page faults, TLBs, etc.).

Let the compare-and-contrast discussions and class assignments begin.
