I'm kind of obsessed with old formats and how they are like a fossil record of a period of computing that's gone, and that I have nostalgia for. Wavefront was such an alluring application when it was around. The peak of Silicon Graphics era mystique. It was one of the big 3 from the time that included Alias, and Softimage. Then, over time there were various mergers and acquisitions and all the apps started to kinda meld into a commonality – we lost a bit of the unique magic of all these different approaches and opinions.

You can see something similar in the MIDI specification. There's actual manufacturer codes and if you read through them you get a kind of 'who's who' of the synth era.
