It's nice to have screenshots with a little buffer, background, and dropshadow. But I really didn't feel like spending any money to one of those fancy screenshot services so I made one with bash / imagemagick. I generated my background image with DALL-E.

You can see an example of the image here: https://twitter.com/samcraigjohnson/status/17321947801747621....

Shadow is adjustable with https://imagemagick.org/script/command-line-options.php imagemagick -shadow parameter.
