The LED wall went live in the fall of 2018 but other projects kept me from fixing a few bugs. I felt compelled to fix them before publishing. The frame rate last year was abysmal. I got help from a few wizard FPGA designers at toorcamp 2018 managing the onboard memory.   We changed the way we wrote out to the LED panels and finally last week I got the frame rate up to 20fps.
