CHM has an original Al Alcorn inspired "My other computer is a Cray" T-shirt that your received if you used the machine. Here is a hacked up picture of the front and back. I was thinking of buying the one on eBay, but I'd have no use for it since I don't wear T-shirts ever.

The original rationale for Apple buying the Cray and Sam Holland's whole organization within ATG was just weird. One little lie about "Pencil Test" being rendered on Macs was that the ending title sequence was actually done on the Cray. I was the person who did the frame by frame transfers though the Abekas frame store, then copied all the frames out to Sony D1 tape.
Here is a better quality "Pencil Test Behind the Scenes" than what is on YouTube, done from my VHS copy a long time ago.
