One-Shot Photon-to-Earth Ride: Sonnet 5.5 Builds an Interactive Solar Journey in 55 Minutes

uzih · reddit · 2026-09-29

A Reddit user one-shot an interactive website riding a photon from the Sun to Earth using Sonnet 5.5 in Claude Cowork web. The build took about 55 minutes and consumed just 5% of the $20 weekly limit with a single prompt.

The trick: real-time light travel is far too slow to watch (it takes 8 minutes), so the site makes the journey perceivable. The author first workshopped the idea in a separate Sonnet 5.5 chat and had it craft the final one-shot prompt. Live at ride-a-photon.somewhere.site.
