Dev one-shots an interactive Platonic solids app with GPT-6 Astra in about an hour

- revodavid shared an educational app, "Becoming," built with GPT-6 Astra: it one-shotted his original concept, followed by a few hours of prompt refinement. The app is an interactive Platonic solids study with dual paths (decreasing faces / increasing vertices), drag-to-rotate, zoom, a timeline, and multi-speed playback.
- Companion posts add key data: via GitHub Copilot it was faster than expected and priced at 1x (same as Sonnet); a 5-line prompt got it running in 10 minutes, the output adapted for mobile unprompted, JS code was compact, and the final version took about an hour of his time.
