The Size of Everything

I am absolutely _loving_ The Size of Everything (https://armchairastronautics.blogspot.com/p/size-of-everything.html).

I printed it out.

Is the source code in your git at all?

Also, could you add a watermark/url? That would make it easier for me to share on social media so I don't have to retype "by Olaf Frohn" everywhere as it would be included.
