• ## #DigitalGeometrySketchbook Days 21 to 30

Throughout the month of June 2021 I created a daily maths art piece, each one using different software or different techniques, as part of the #GeometrySketchbook challenge on Twitter. As mine was all digital artwork, I used the #DigitalGeometrySketchbook tag. Here are the results of days 21 to 30.

• ## Dancing Triangles: Sunday Maths Animations Week 9

A spiral of dancing trianglesâ€¦just because.

• ## Pythagorean Spiral meets Pursuit Curves: Sunday Maths Animations Week 8

Earlier this week I was proofreading a book that mentioned Pythagorean spirals. I had seen them before but never thought about them too deeply, so I gave them a try in GeoGebra. I filled them in with curves of pursuit, just for fun!

• ## More Cardioid Rainbows: Sunday Maths Animations Week 7

Week 7 of my Sunday Maths Animations is another one that started out as a cardioid. Varying a different parameter gives a completely different effect.

• ## Cardioid Rainbow: Sunday Maths Animations Week 6

Week 6 of my Sunday Maths Animations started out as a cardioid, but quickly became something else.

• ## Pythagorean Tree: Sunday Maths Animations Week 5

Week 5 of my Sunday Maths Animations is a Pythagorean tree, drawn point by point.

• ## Rhodonea Spheres: Sunday Maths Animations Week 4

Week 4 of my Sunday Maths Animations is my old favourite the Rhodonea curve, rendered with spheres. The ending is extremely satisfying!

• ## Infinitely Zooming Circles: Sunday Maths Animations Week 3

Week 3 of my Sunday Maths Animations grew from a puzzle at February’s MathsJam that involved calculating the shaded area in a shape involving infinitely recursing circles. Can you tell which circles are changing in size and which are staying the same?

• ## Circles on a Harmonograph Curve: Sunday Maths Animations Week 2

For week 2 of my Sunday animations I’ve stuck with circles, this time on a harmonograph curve (which is a relation of the Lissajous curves).

• ## Circles on a Lissajous Curve: Sunday Maths Animations Week 1

I’ve been enjoying making animations in Geogebra recently, and have decided to try publising one every week on YouTube. Here is week 1.
