What it does

Create music visualizer videos in your browser — GPU-rendered, beat-accurate, up to 4K. No upload, no render queue, no account. Free to use.

Most of which is you deciding which theme you like. Drop in an audio file, add your cover art, pick a look — and export it up to 4K, straight from your browser. No upload. No render queue. No account. Your music never leaves your machine. Name it, pick landscape or portrait, pick a resolution. The orientation is chosen per project, so the composition is built for that frame rather than cropped into it — landscape for YouTube, portrait for Shorts, Reels and TikTok. It's analyzed on the spot. The app runs a full pass — spectrum, onsets, tempo, beat grid — over the entire song before it draws a single frame.

  OwnTime – a chess clock for your day's priorities▲111

  I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up. One…
