I have been play testing our new puzzle which is _NOT_ a jigsaw puzzle. It’s been super fun. How long do you think should an easy puzzle take? What should each one of these sets of tiles be called? Internally we’ve been calling them scenarios but also considered “board” or just “puzzle”

Word of the day: boletinoid Mushrooms having a structure intermediate between gills and pores. As seen in this ash-tree bolete. (I love these) #fungifriends

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

Reminder: open studio tomorrow from 10 to 4 PM at our workshop in Palenville. Look for the nervous system sign at the top of our driveway n-e-r-v-o-u-s.com/blog/?p=9816

ASK AN ENGINEER 8/13/2025 LIVE! youtu.be/C-6sr1VylhU

Visit Nervous System this weekend for our first ever open studio! 8/16 10am-4pm in Palenville, NY (near Catskill) n-e-r-v-o-u-s.com/blog/?p=9816

We’re headed to Seattle for a week. Going to see friends, go tidepooling, maybe Chihuly

The Hyphae Lantern is done! Next step is crating it for shipment

I feel like I already knew this, but if you naively run PBD in parallel without accounting for overlapping constraints, it’s only stable with a stiffness <= 0.5

I've been implementing a limited version of Position Based Dynamics in CUDA for our latest sculpture project. I'm always surprised how inflexible most APIs are making them completely unusable when deviating slightly from the intended use case (I'm looking at you NVIDIA)

It’s been awhile but puzzle stream is back tonight in about 15 minutes twitch.tv/nervousPuzzles

My new automatic rivet loader isn’t very efficient but it is very cute

The Hyphae lantern is taking shape #sciart

We’re opening up our studio to visitors on August 16th. Mark your calendars! We will have demos, you can shop our jewelry + puzzles, and also get sneak peaks of various sculpture projects we’re working on (in Catskill, NY)

Logarithmic maps are incredibly useful for algorithms on surfaces--they're local 2D coordinates centered at a given source. Yousuf Soliman and I found a better way to compute log maps w/ fast short-time heat flow in "The Affine Heat Method" presented @ SGP2025 today! 🧵

Happy Gosh Gathering from Dinacon!! 10 years ago @goshcommunity.bsky.social made a goal to make open science hardware ubiquitous by 2025! The time has arrived and we are celebrating #opentools here with 53 people at Dinacon! #openscience #opensource

This piece is the proof of concept for a new bilayer construction process. Two sets of panels which are perpendicular to each other interconnect to make a rigid surface. The prototype is constructed from just 1/16” sheets of plywood yet holds it shape when suspended from a single point

Some late night sculpture prototyping

Speaking of SIGGRAPH, as usual I'm assembling a list of the physics animation-y subset of the technical papers, with links: https://www.physicsbasedanimation.com/2025/05/19/siggraph-north-america-2025/

Here’s another clip from my video on expanding rack and pinion mechanisms - an expanding pythagorean triple triangle. There’s a reason why it’s easier to make this kind of triangle! Full video at

The most vital thing you can do right now is spread this message offline to normies. There is no "unrest", there's a protest. It has 400 people. LA does worse when the Lakers come in 3rd in a season.

Tonight on stream we'll be the the Large Marbling Infinity Puzzle. It's a tiling puzzle made in collaboration with @amandaghassaei.bsky.social using a simulation of paper marbling she created. At 363 piece, it should be one of the harder puzzles we've done. Join us at 7:30PM EST

Puzzle stream is going to delayed until tomorrow. But we just got 8 guinea fowl keets (babies). Should we have a guinea keet stream instead?

Revisiting one of my favorite girls…time to remodel her assembly 🛠️

If anyone will be at SIGGRAPH in Vancouver this August, I'll be running a labs session about p5.js 2.0! come out and say hi!

I've been building some little tools recently like this gyroid cropping tool. Let's us quickly design shapes where you rotate and scale a gyroid inside a mesh. It's raymarched in a shader so it runs it real time. Based on this shadertoy www.shadertoy.com/view/MffGzS

We're live

I am very tempted to back this kickstart for a fiber laser from Gweike, even though I basically never get things from kickstarter. Anyone with fiber laser experience have opinions? I know Gweike is a reasonable Chinese brand www.kickstarter.com/projects/gwe...

We're having a puzzle sale for Father's Day! 15% off with code DAD (ends 6/4/25) n-e-r-v-o-u-s.com/shop/line.ph...

Tonight on the puzzle stream, I'll be starting the Rainbow puzzle, a favorite of my daughter's. Join us at 7:30 EST twitch.tv/nervousPuzzles

Puzzle time twitch.tv/nervouspuzzles

Going live! Will we finish tonight? twitch.tv/nervousPuzzles

We continue to work on the eclipse puzzle on tonight’s stream. This puzzle is harder than I thought it would be. I wonder if the moon side would be easier or harder n-e-r-v-o-u-s.com/shop/product...

🔷🦀 TetWeave: Isosurface Extraction using On-The-Fly Delaunay Tetrahedral Grids for Gradient-Based Mesh Optimization is accepted to #SIGGRAPH2025 (TOG). Done in collaboration with @rubenwiersma.nl, Philipp Herholz, and Olga Sorkine-Hornung. But why a new shape representation? (1/9)

A thread on our new, also awesome, Siggraph paper "Linear-Time Transport with Rectified Flows", by K. Do, @dcoeurjo.bsky.social, P. Memari and me. Paper here: perso.liris.cnrs.fr/nicolas.bonn... Results in video: youtu.be/EcfKnSe6mhk

"On a weekly basis more than 90% of people use weather forecasts, job market reports, food safety warnings and other information that is based on federal science. But only 10% ... are concerned that cuts to federal support for science might impact their access to [it]." www.npr.org/2025/05/06/n...

Periodic reminder that we make unique wood puzzles! Smaller ones make great gifts but go for an Agate or Bismuth if you want more of a challenge n-e-r-v-o-u-s.com/shop/line.ph...

Last week we completed the Neuron Puzzle in 4:17, our hardest puzzle yet. Tonight we begin the Eclipse Puzzle. The double sided image let's you incrementally eclipse the sun when you assemble it. Join us on stream tonight as I try it for the first time. twitch.tv/nervousPuzzles

The NYT wants you to think universities became dependent on government. This is false. The government invested in the national research infrastructure by competitive grants to universities. The taxpayers built this. It got us to the moon. Won the Cold War. Created Silicon Valley. Made the McRib.

We missed a week, but we're back with collaborative puzzling on twitch! Trying to finish the Neuron Puzzle. Live now twitch.tv/nervousPuzzles

We often use discretization to approximate continuous laws of physics, but it also goes the other way: You can use continuous equations to approximate the behavior of discrete systems! Here we'll see how electrical circuits can be modeled using the Laplace equation Δφ=0. [1/n]

Come puzzle with us on twitch tonight starting at 7:30 EST. We will be trying to finish the Neuron Puzzle. Unfortunately we already did all the easy parts www.twitch.tv/nervouspuzzles

Love the prototype puzzle we just received from @nervo.us !! Really satisfying cut pattern.

The Trump admin has just detained Mohsen Mahdawi, who: –has green card –was Columbia Buddhist club president –saw his best friend shot & killed by Israeli soldier –said "we are against antisemitism because antisemitism is a form of injustice, and injustice anywhere is a threat to justice everywhere"

Harvard redid its whole homepage to push back against the administration’s demands. I mean, this is just a website but I think it’s kind of a great PR move: www.harvard.edu

Published an op-ed for @cnn.com: “Nobel laureate: I owe America my success. Today, its scientific future is in danger.” A personal reflection on what’s at stake as science funding gets slashed. I’d be grateful if you could amplify both in and beyond the science world. www.cnn.com/2025/04/09/h...
