Used the laser cutter to make a holder for my class set of spirographs — for the lessons I like to do my students need to know how many teeth the gears have. They write a program that produces the same curve using turtle. (with older students we do the trig, which I just call “magic circle functions” for the grade fives)

This will make it all go much smoother!
This is 8 sets packed into one box!

Always remember : ‘Computer’ was the word for a woman who did calculations.

There’s a reason that the patterns for jacquard looms were effectively the first computer programs.

Knitting and crochet patterns are essentially machine language code.

Quilting traditions incorporating geometric patterning and permutations mixed with optical effects is all of a piece of this. (Pun very much intended.)
