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.

Nowadays it also supports .NET, COM and ObjectARX.

Just like Gimp eventually added support to Python alongside Script-Fu.

Which end up reducing the interest to reach out to Lisp languages.

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.
