How it works

Buy a slice of a global digital wall.

The billboard is a 10,000 × 10,000 pixel world. Each pixel is a real unit for sale, and each selected block can be purchased with a clear, transparent price.

1. Explore the wall

Use pan and zoom to move around the billboard. The wall is rendered efficiently on a single canvas so the experience remains smooth even at large scale.

2. Select pixels

Click a single pixel or drag a rectangle. The app converts the pointer position into the exact billboard coordinate, so the selection matches the area you choose.

3. Review pricing

The selected area shows total pixels, estimated size, and currency-based pricing in real time. This keeps the decision transparent before checkout.

4. Purchase

Once a selection is confirmed, the system can route into a checkout and order flow. This prototype is built with the right product shape for future payment integration.
