DevDay swag turned into Open.Dotlet, a 30-key physical prompting tablet for Codex

Inspired by OpenAI DevDay, a community developer turned the swag into Open.Dotlet: a 30-key prompting tablet where each key triggers a saved Codex task with one press, with results readable in the app. Fully open source, it runs on macOS (Apple Silicon) and Windows 11, reuses local Codex CLI sign-in (no separate API key), and the alpha executes one read-only task at a time. The promo film uses OpenAI's AI voiceover and ElevenLabs music; an OpenPromptlet connection is planned.
