A nice joke but... this is an sgi, they pretty much invented accelerated graphics. Original glquake used minigl which was GL cut down and neutered to fit within the glide api, these guys invented and their systems could run the full GL. There actually was a very nice accelerated port of Quake on the demo disks included with the system.
It's already done as Quake it's libre source and if the GLIDE headers for SGI match the ones of the 3DFX ones from the Linux implementation it would be just a matter of path setting and a few ifdefs.
