I had a keychain of a CPU in resin for a long time, Intel would sell them in the gift shop because they were failed prints.

Also, in SC5? there was a hallway that had a bunch of plaques from partner companies... and what was awesome was the amount of "Engrish"

Some of the comments were along the same line as "for great justice" (if you are aware of that old meme)

Got on of these keychain chips in the late eighties from a friend whose dad worked at IBM. I remember that it came with a comparably cheap key ring clip and that the edges wore off nicely over time. Funny to be reminded of that. Thanks for mentioning.
