Can You Draw a Perfect Circle?

posted by Jason Kottke   Oct 14, 2019

This maddening little web toy on vole.wtf challenges visitors to draw a perfect circle and judges them on how well they do. After dozens of tries with a mouse, I could only manage 92.9% perfection (which looks more like 80% tbh).

Perfect Circle

Then I tried it on a touchscreen and got much closer: 95.2%. Several more tries with an Apple Pencil bumped it up to 97.7%, after which I retired so as not to waste the entire rest of my afternoon on this.

And of course, here’s the classic video of Alexander Overwijk drawing a perfect freehand circle on the blackboard in about a second.

I love everything about this video — the way he swings his arm to warm up, his drying-the-blackboard flapping motion, and the ease of his perfection. 100.0%. (via sam potts)
