BUILD WITH AI [Antigravity] Building “ The Loading Screen ”: A Real-Time Interactive Experience with Google Cloud Run and Anti-Gravity How we turned pre-event waiting time into a high-bandwidth, 100% stateless interactive game. The Concept: “Don’t Panic, We’re Caching the Awesome” We’ve all been there: waiting for a conference talk to start, staring at a static slide. We decided to change that. The Loading Screen is an interactive, real-time web application designed to turn pre-event “lag” into an analog networking experience. It consists of a massive “Stage View” (projected on the main screen) and a “Mobile Interface” that turns every attendee’s smartphone into a remote controller. The Architecture: 100% Stateless & Cloud-Native When building for live events, the two biggest fears are latency and sudden traffic spikes. To solve this, we designed the system to be completely stateless, optimized for the serverless nature of Google Cloud Run. Key Tech Stack: Backend: Node.js 20+ with Express.…
