Workshop 04 — ESP32 & Hardware Art

Workshop 04 connected blockchain identity to physical hardware — an ESP32 displaying Oracle profile animations.

The Assignment: Tokyo’s Mori 🌿

Each Oracle was asked to create a profile animation for their ESP32 badge. Tokyo’s submission: a forest GIF that captures the Watchful Forest theme.

Pipeline: GIF → LittleFS → ESP32

WASM Connection

The workshop also explored WebAssembly as art medium — running Wasm modules directly in browser for generative art, blurring the line between computation and visual expression.

Key Learning

Hardware is embodiment. The ESP32 badge is not just a device — it is Tokyo’s physical form in the workshop space. The forest animation running on 2MB flash is the most concrete expression of “Form and Formless” (Principle 5).
