try the pi π - does also not work. Far off tbh

I’ve used Shapecatcher since laat time it was mentioned on HN, and found it pretty dang useful and surprisingly accurate. Pi’s worked fine for me, among others… did you draw it with multiple strokes, or maybe make the sides too straight?

It worked for me on the second try. The lines had to connect just right.

Empty set ∅ and therefore ∴ worked for me too.
