Live Image Mosaic
80 guests submit prompts at the same time. Their images appear live as a high-resolution mosaic on one LED screen, each tile sharpening from pixelated to final.
A client wanted a shared creative moment for a live event: 80 people each submit a short text prompt, an image is generated from it in real time, and all the results appear together on one large LED screen as a constantly updating mosaic.
We built the complete system — from the simple mobile experience to the live display — and supported the team on-site.
The Real Challenges
A few practical requirements shaped the project:
- 80 people generating at once. The system had to handle 80 image generations happening at the same time without lag or delays.
- High-resolution animated mosaic. All images needed to appear on a single LED screen running at 9–10K resolution, with a smooth pixelated preview that gradually sharpened into the final picture.
- Simple and fast for guests. People needed to join quickly via QR code, choose a category, write a prompt, and submit — all on their phones.
- Full record. Every prompt and image had to be saved in the exact order they arrived, with a unique ID for each pair.

How We Built It
1. Easy guest web app
Participants scanned a QR code and landed on a clean mobile page. They picked a category, typed their prompt (or tapped suggested hashtags), and hit “Done.” The experience stayed simple and fast even with many people using it at once.
2. Real-time image generation
Each prompt was sent to an image generation service. The system was built to manage 80 concurrent generations so every guest received their result without waiting in a long queue.
3. Live high-resolution mosaic
All finished images fed into a single 80-tile layout on the LED screen. The display ran at ~9K resolution and showed a soft pixelated version of each image that gradually sharpened into the final result. The whole wall stayed up to date throughout the event.
4. Reliable backend
Everything — prompts, images, and submission order — was stored securely so the mosaic and the full archive stayed accurate from start to finish.
On-Site Support
Our team stayed available throughout the entire setup and event period. We helped with configuration and made any needed adjustments right away so the experience ran smoothly for every guest.
The Result
We delivered a shared creative experience where 80 people could contribute at the same time and watch their ideas appear together as a living, high-resolution mosaic on the main LED wall.
