See Mini-G look at this fine piece of stripey art:
Isn’t that interesting, full of nuance? NO — it looks totally boring. But Mini-G is actually looking at it at an angle, which turns out to be a completely different story.
No more simple stripes! And while it’s no Mona Lisa*, it’s pretty cool to see the shapes appear just as you start to walk away in search of something less vertical to look at. Even better, it’s simple knitting. REALLY simple knitting, just knits and purls, where using stockinette stitch makes a color fade into the background when viewed from the side, and using garter stitch makes a color stand out. There’s a great explanation here, where “great”=“uses legos”.
This comes from Woolly Thoughts (“In pursuit of Crafty Mathematics”) and their newish illusion site. It’s a free pattern — Woo hoo! — and not that I’m suggesting that you knit during meetings or anything, but if you DID knit during meetings this particular pattern is simple enough that you can do it without being distracted from the Important Conversations and Presentations, and then you can feel good at the end of two hours that you made quite a bit of progress on your knitting whether the meeting led to a resolution or not, plus you get to point out that you’re really doing mathematics if anyone asks what you’re knitting. Win-win!
* though there is a pattern for that.
