This is quite nice! I might start using this.
Some things that would make this nicer:
- Add a downloadable, ready-to-use bin as a release.
- Change the background-gradient. For me, it is a bit too close to the bright pink used on old VGA-games, so I initially thought it was an error.
- Add option to also copy those lines to clipboard, or upload them to pastebin or similar. The url could then be embedded within the generated image. Perhaps this does not fit into the scope, but it could be nice.
- Add a short instruction on how to use this within an editor. For instance, perhaps a short vim-binding from a selection could be added to the readme?
- Why is there a link in the readme to a wikipedia-article on Fast inverse square root?
