Pixelated Physics
Pixel-art characters and designs, each built on one real piece of physics.
Tees, stickers, hoodies and mugs for science fans, students and the endlessly curious.
We exist because we think knowledge is for everyone.
The product is the character, not a quote on a shirt.
Deep Cuts: the less-told corners of physics, drawn in pixels.
How to read a design
Pixel art, built on one real piece of physics.
The key relationship behind it, written the way physicists write it.
What it means, in plain words.

· Nuclear & Particle Physics
To fuse hydrogen on Earth you need a gas at well over 100 million degrees, and no material wall can touch it. A tokamak solves this with a doughnut of twisted magnetic field. Here is how the fields are built, what the Lawson criterion demands, and what JET, ITER and NIF have actually achieved.
