The engine
Renders every app at 32×32, bakes loops into GIFs the panel plays on its own, streams only what changes, and reconnects by itself.
Free & open source · unofficial · for iDotMatrix 32×32
Turn your iDotMatrix into a live desktop companion.
DeskDot is the all-in-one app for your iDotMatrix: 100 apps, 31 multiplayer games, live data from 45+ free sources, a studio for your browser and phone, and an MCP server so AI agents can see the panel and drive it.
No install: the full engine runs in the tab and talks to the panel over Web Bluetooth (Chrome, Edge or Opera on Windows, macOS, ChromeOS, Linux and Android; on iPhone use the Bluefy browser).

What it is
One engine owns the panel. Everything else talks to it.
DeskDot runs on your computer (or a Raspberry Pi) and keeps the panel's Bluetooth link smooth. You drive it from a studio in your browser, from your phone, from scripts, or by asking an AI agent.
The studio
Library, playlists, presets and live settings with an LED-accurate preview, on desktop and phone. See the studio.
The MCP server
21 tools let Claude and other agents look at the panel, run any app, change settings, draw pixel art and notify you. Set it up.
Real renders, not mock-ups
Every app, exactly as the LEDs show it
Each preview on this site is rendered by DeskDot's own engine at 32×32, the same frames your panel gets. Here are a few; the explorer has all 100.

Fly Brain
A fruit fly driven by a model of its real visual circuit (FlyWire connectome): it hunts fruit, dodges a looming swatter. Its neurons firing and the keys it presses play in the studio's 3D Fly view.

Get going
Two ways in, about ten minutes each
01
Let your AI agent do it
Paste one prompt into Claude Code, Gemini CLI, Codex or Cursor. It installs everything, starts the simulator and waits for you before touching the panel.
AI setup 02Do it yourself
Ten short steps from installing uv to a live panel, each linked to the file that explains it. No panel yet? The simulator runs everything.
