While not Common Lisp I've always found it pretty cool that AutoCAD shipped with a Lisp, making the language technically a hugely deployed commercial success.
Were it not for early exposure to Autolisp I would not have appreciated Lisp or Lisp-based systems, like Emacs, the way that I did. I might've ended up whinging that they didn't use a mOdErN language like JavaScript.
Autolisp definitely sent me down the left-paren path.

Indeed, Arc's been running on Common Lisp for a while now!
Until Vindarel gets the TLS working there's also a direct URL: (<https://simple.photo/vindarel/c352e2c0177b24786fb40041657485...>). It's a bit of a shame that there's no indication to what application each screenshot is from.
I like how the disclaimer went humble bragging about the range of usage.
