Had a terrifying moment earlier where I thought I’d lost the original pixel art for my Math Sampler-- false alarm, luckily! But when I did find it I found a bunch of rejected square ideas, too, and it’s fun to see how some of the ideas got reused later on! From the top:
Newton’s Cradle-- cut because it’s not so much ‘mathematics’ as ‘physics’. Though I would love to make a physics-themed pattern someday...
Overlapping light colors. This one’s not even a little bit mathematical, so I have no idea why it’s in there? Besides the fact that stitched optical effects are super cool to look at. (case in point)
Hilbert Curve-- tragically had to be cut because it couldn’t fit nicely in a 30x30 square. I made up for it by putting it in one of the Pi Day Puzzle Stitch-a-longs and one of my Octobit pieces, though. :)
A Pie! Certainly the prettiest of the cut squares, but again, not mathematical enough. I remember being sad to cut this one, but just like the HIlbert curve I got to stitch one later, for Pi Day, a couple years down the line.
Binary numbers: fit the theme, but not the look. This is another one that showed up in a Pi Day Stitch-a-long, where it fit the vibe a lot better.
