Hi, I'm Caleb Terry.

I make things for fun: small tools, toys and experiments, each built with care for how it looks and feels. They all live here.

Projects

Tools
Free tools for small jobs, right in your browser.
Formatters, converters, calculators and shop helpers. No sign-up, and nothing you type leaves your device.

Overkill
Absurdly advanced tech, explained badly, used for dumb stuff.
Humanity builds miracles of physics and then uses them for the dumbest possible things.
overkill.cterry.dev
Pocket Worlds
Tiny realistic 3D worlds that sit on your table.
Orbit an alpine lake, a red mesa, a rainforest or a little city; squeeze clouds for rain, spin up a twister, fling the locals.

Marble Run
A glass marble run on a tabletop, in your browser.
Snap tubes, spirals, funnels and splitters together on a peg board, drop marbles in, and share your run as a link.
