The story behind GitHub HQ's live open-source wall: how Gitmos was built in 2020
omojumiller · x · 2026-10-27
Former GitHub AI engineer Omoju Miller recounts building Gitmos in 2020 — the live visualization wall at GitHub's SF HQ showing pull requests arcing between cities, a Trending Developers list, and real-time data streams that developers photograph themselves on. It grew from Cerebro, an installation prototype built on the public GitHub Events API and an open-source graph explorer, and he drove it end to end — writing the RFP, hiring the creative team, and building the data pipeline himself — despite it having no place on the roadmap.
