Gnomon by Athanasius Kircher. Astrological symbols are arranged around an arch, with grid lines emerging from each. Some cherubs who look like they know what they're doing are in the middle with measuring sticks and a globe.

Hello, my name’s Christian Lawson-Perfect and my main mathematical interest is “everything”.

Before The Aperiodical existed as its own thing, the only outlet I had for my mathematical eclecticism was a series of posts on the Acme Science blog called Aperiodical Round-Up.
