The aperiodic table

XKCD 3242 is titled "The aperiodic table" and looks like this:

Which is cool, but it's not aperiodic like a Penrose tiling. So, with a little (a lot) of help from Claude I create aperiodictable.com your one true resource for the periodic table on a Penrose P3 tiling. Click and drag the canvas to place the periodic table wherever you fancy. Hit Print to print your own Aperiodic Table.

It's a single page that's hosted on Cloudflare Pages.
