Flipper Zero Tools

Two small apps for the same tiny, useless-but-perfect screen: flipper-space-calculators and flipper-generative-art.

Space Calculators

A set of minimalist space- and physics calculators for the Flipper Zero — relativistic time dilation, space-travel figuring, and friends, all on the 128×64 screen for back-of-the-napkin astrophysics in your pocket.

I think I like it because it's so useless but still utilitarian — cyberpunk and gestural. It's a tool for a time/space-traveler who doesn't exist — or maybe does — the kind of thing he'd find handy.

It's also an experiment in pushing what small Flipper apps can do, and imagining utilities that would make sense within its capabilities — using the limits as a method of inspiration. This is what came from that.

Generative Art

I often just leave the Flipper on my desk below my monitor, and my feeling was: why not have it show me little evolving art pieces instead of just the time? What would that look and feel like? Is generative art even possible within the constraints of the Flipper's screen and processor? What does 1-bit generative art feel like? How can it evolve over the course of a day?

This is the answer: a Flipper Zero app that generates animated patterns in real time on the device's 128×64 monochrome screen. It runs ten gradient families — horizontal, vertical, radial, diagonal, sine waves, interference, checkerboard, noise, spiral — and converts each to crisp 1-bit graphics with Floyd–Steinberg dithering, evolving the parameters every second at ~30fps.

Making something genuinely generative look good in 1-bit on a tiny embedded display is the whole challenge — the dithering is what turns smooth math gradients into something the Flipper's screen can actually render without looking like mud.
