Meet the Flummoxagon, a new geometric puzzle game that might just leave you flummoxed. Imagine a mash-up of Pentominoes and Sudoku. Your goal is to fit all the pieces into the hexagon frame but there’s a twist, pieces of the same color can’t touch. n-e-r-v-o-u-s.com/blog/?p=9827

I realized we hadn't updated our headshots in over a decade. It felt fitting to take new photos inside our own work (also featuring @nervousjesse.bsky.social @nervo.us)

Our Hyphae lamps are inspired by mycelial networks. Each lamp is unique. We grow them using an algorithm based on how veins form in leaves. We have a few in stock now: n-e-r-v-o-u-s.com/shop/generat... #sciart

My daughter's favorite was the sea stars. We saw Ochre sea stars in purple and orange. But the purple is much more common. Scientists think the colors come from their diet (purple ones eat a lot of mussels) @echinoblog.bsky.social has an article on it: echinoblog.blogspot.com/2010/03/why-...

I think my favorite creature I saw was the worms! These feather duster worms use their plumage for respiration, filter feeding and sensing. If you disturb the water they quickly retract into their tubes

Apparently horseshoe crab compound eyes have around 1,000 light sensing units called "ommatidia." They have a conical shape as seen in this micrograph www.optica-opn.org/home/newsroo...

horseshoe crabs accumulate so many interesting patterns on their shells from cracking, barnacles and other encrustations over their long lifespans
