pandadraw

Tangible Cloud Oracle - Marloes de Valk

A collaborative terminal drawing prototype built with p2panda for HDSC2026. pandadraw can be used as a medium to demonstrate the ideas of limited availability, (re)networking network and seasonal computing. It's also a pretty fun way to draw ASCII art with friends 🩷💙🩶

Platform support

• amd64
• arm64

More platforms (e.g. macOS, windoze) available on request and with your support as I can't build some of them myself. It would be nice to support macOS in the near future.

Install

wget https://git.coopcloud.tech/decentral1se/pandadraw/raw/branch/main/target/x86_64-linux-musl/pandadraw -O pandadraw
chmod +x pandadraw
./pandadraw

Usage

Offline or local network

A default topic is hardcoded into the CLI options which starts all peers off on a shared canvas. Pass -new to start a new topic or pass -topic <hex> to specify your own.

If you're alone, open it up in multiple terminals and draw with yourself 😂

Remote peering

You need to provide the SHARE hex value from the UI to the remote peer.

pandadraw -peer <hex>

Controls

• CTRL-C: Exit
• CTRL-S: Toggle color
• CTRL-E: Toggle emoji

Features

• Real time or async collaborative drawing. Each topic contains a canvas which is persisted locally and published to peers. As long as one peer maintains a copy of the topic state, all other peers can reconstruct it later.
• Offline-first or local/global p2p connectivity. Draw or share your previous drawings offline in your local network. Remote peers only need to connect to single peer to have their changes published to the rest.
• Minimal TUI with peer presence, configurable emoji and color settings. Node/topic sharing details are also shown.
