A walkinto forever.

A portal to another dimension at the world's biggest space congress: rough rock on the outside, and on the inside a corridor of colour that folds back on itself without end — with you in it.

The brief

Buble Studios wanted delegates to step out of the expo hall and onto an alien exoplanet — and every world needs a door. The brief for the cave was exactly that: a portal to another dimension. Rough, rocky and dark from the aisle; the moment you stepped through, a rainbow running away to forever. (The world on the other side grew a tree with senses.)

The portal

From the outside, a cave: sculpted rock, no hint of what's inside. Through the mouth, the walls fall away — a chamber where every surface runs to infinity in colour, and the stepping stones glow to lead you through.

The Infinity Cave from outside — a dark rocky portal opening onto a mirrored interior of endless multicoloured LED lattices, with green stepping stones leading in. — Rough rock outside, infinity inside.

Boxes of forever

The trick is in the walls. Each panel is a custom infinity box — a two-way mirrored window over a chamber of mirror and addressable RGB LED tape — so every box repeats its light away to nothing.

Every box was individually mapped: hue, saturation, brightness, movement and animation, rippling through the whole cave as one programmable surface. A high-resolution LED screen closed the far wall, and a camera at the cave mouth fed visitors themselves back into the loop — so you stood inside an infinity that had you in it. It earned its nickname before the first day was out: the selfie station. The queue never went down for five days.

"I've never seen a reaction to an expo stand like this before. It's blown everyone's minds."
