I think someone spotted them a while back, but they're certainly worth another look!
Indeed, these are beautiful, high-quality handmade caps. It's a hilarious idea, too—anyone who knew vintage computers and saw them would do one of those cartoon-style double takes where their eyes go out on springs. :?) Unfortunately, at $285.50 per set, I doubt many of us will be ordering them soon.
The same vendor also makes a bunch of fun, unique single caps at $6 each, which is quite reasonable.
