The SGI Indigo (https://en.wikipedia.org/wiki/SGI_Indigo) was quite the advanced piece of hardware back in the day (1991), where it could be thought of as the graphics "spiritual successor" to the color NeXTstation (1990) https://en.wikipedia.org/wiki/NeXTstation, which could in turn be thought about as the graphics "spiritual successor" to the original Amiga 1000 in 1985 (https://en.wikipedia.org/wiki/Amiga_1000).
(Of course, later in computer history, discrete graphics cards (the ancestor of the AI accelerator card) would grow in scope and power, eventually surpassing graphics capabilities that were specifically tied to, or bound to, a specific manufacturer or computer type -- but the SGI Indigo was a revolutionary milestone for its place and time in this history! They are still collectible today, and I highly applaud the author(s) of this project for bringing back (on FPGA with Verilog!) this quintessential piece of computer / computer graphics history!)
Anyway, looks beautiful!
