There’s still time to order Nervous System jewelry (and puzzles!) for holiday delivery. My daily necklace is the Reaction Möbius Necklace in 3D-printed stainless steel. It's virtually indestructible and doesn't tarnish n-e-r-v-o-u-s.com/shop/product...

Merry #Crustmas! I've added the new whimsies from our Ocean Tapestry and Bioluminescence puzzles to the custom puzzle app, including a crab and scorpion. I've also decreased our lead time so you can squeak in a custom puzzle order before Christmas.

Today, the children discovered the box of hundreds of “hat” tiles, the aperiodic monotile. Sometimes it’s nice to have your own puzzle factory.

Of all my photos, this is easily my favourite I've ever taken. This amphipod is legitimately about 1mm in size. So small your eyes can't make out any details on it. They refuse to sit still. They run away from the light. It just looks like a grain of sand.
Genuinely a 1 in a million shot.

A rare photosynthesizing sea slug has been found off N.S. Here's why scientists are excited | CBC News
Researchers believe Elysia chlorotica holds promise for medical advances, but it's been too elusive to study.

ahah IT WORKS look it's a C² dual quaternion B-spline!!
this is interpolating *poses* in dual quaternion form, coupling position and rotation, instead of treating them independently (this is a really neat thing!!)
