I make games, physics simulations and tools that run in the browser. Here is a map of everything in orbit.
Departure The Solar System, 26,700 light-years from the centre of the Galaxy. Destination Sagittarius A*.
At the centre, Sgr A*Starlight is bent live around it: gravitational lensing computed in a shader. Hover the stars: each one is a project.A black hole of four million solar masses, around which this whole catalogue orbits. Start the 3D
§ 01The pilot
I like making projects. A lot of things interest me, from games to physics, maths and small everyday tools, and they often end up as something you can try right here.
Some were born over a weekend, others kept me busy for months. I keep them all here, finished or not, because that's how I learn: by building.
An idea, a question, a project? Write to me: hugo.hismans@gmail.com

The journey stops at the brightest projects. Each stop is a real star on the map: the camera settles on it while you read.

Get your friends to guess a word, one single-word clue at a time
The online clue game for friends: a secret word, one-word clues, a timer. It rejects clues that are too close and forgives typos.

Spin the globe and find the country: flag, capital, currency, motto…
A globe you understand in a second, dressed as a night-time nautical chart: flags, capitals, currencies, in French and English.

Show your cube to the camera and it tells you how to solve it
Show your cube to the camera: the app reads the colors, computes the solution and animates it in 3D, move by move.

Sagittarius A*, computed pixel by pixel, sixty times a second
A real black hole, computed pixel by pixel by a shader and checked against theory, explored from a ship with voice and music.

An ink-washed world, with portals that change your size
An ink-and-paper world crossed by recursive portals that change your size. Two months of work, 223 commits.

Bluff with dice under the hat, around the table or online
Liar's dice poker around a green felt table: on a single phone or online with friends.

No star matches. Try “Three.js”, “quiz” or “Firebase”.
Map key: each star is a project. Its size follows how bright the project is, its colour its cluster; thin lines link related projects. Numbers HH·001 to HH·047 assigned by date of first commit.
