Apps I have built.

A macOS audio plugin you control by how loud you play. Quiet playing gives one set of effects, playing harder gives another.

Danish radio as a physical panel in the menu bar. Six pads for the national stations, and a dial that reaches into the archive.

A walkie talkie in a browser tab. Nine channels, one talker at a time, and an FM dial everyone on the channel shares.

A grid of lenses laid over a picture, each sampling from somewhere slightly else. Turn the knobs, export a still or a loop.

The starting point for my web apps. Shared typography, spacing and React components, with two visual styles I can adapt for each project.

Avatars I drew by hand. Mix the eyes, nose and mouth from ten faces, and the same name always gives the same face.

A scratchpad that appears when you press a key and disappears when you are done. Lives in the menu bar, and it answers sums.

Click comments on YouTube and turn them into clean images and short animated clips, redrawn from the text so they stay sharp.

A writing app with no server. Your text is packed into the web address itself, so sharing the link shares the writing.
