(Mathhombre) Miscellanea
This is an old one, but brought up again by Patrick Vennebush in a mathprank post. Wanted to dynamicize it by making the table customizable, and animating the check comparison. If you know which table is larger, see the gif below. Sketch is at GeoGebraTube.

Yeah! Jennifer Silverman (tumblr, site) built this in response to the animation going around the other day on the sum of the squares.

Artistotle’s Wheel.
Quick version of the classic paradox I made up for class since we’re discussing infinity today. What’s wrong with the picture?
Edit: GGB sketch, by request.

From a Futility Closet post. GeoGebraTube here, think aloud about making it on the main blog.

Some beautiful dynamic #mathart from Edmund Harriss. Via Center of Math. Direct link.

String Art in class today, so I wanted to make a simpler tool for my intro to math students. On GeoGebraTube.

EDIT: looks like the animated version isn’t animated. Sigh.

That trig reference image needed dynamicization. How’s this? On GeoGebraTube.
