(Mathhombre) Miscellanea

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.
In related news, @JoeKargula found this nice GeoGebra trig activity on the Pythagorean Identities by HaileyMF.

How would you describe the pattern? Is there a pattern to the number of squares in each step?Is there a pattern to the number of triangles in each step?What do you notice about the rhombus-shaped gaps?Inspired by Pattern 80 by Simon Gregg at visualpatterns.org from Fawn Nguyen
On GeoGebraTube, too. There are three tools, for quickly making a triangle or square or three triangles on a square.

Sweet tessellating polygonal line art.

I made this as prep for a different mathart idea (Intersections of a rolling circle…) that didn’t work out. But it’s still a pretty nice two-gear spirograph.

On GeoGebraTube for playing. Any other feature ideas?
