I’ve seen a few of these RPi clusters (obviously none this big), I think the main reason people make them is to demo distributed systems or build a homelab cluster(sometimes they will argue its cause of the power efficiency). Also they are usually a nerd magnet so it makes for a great conversation piece as this probably was for their convention.
