## The Brief

### Make a whole tour group feel a gun that was never installed.

At the **Tvrz Hanička** fortress in the Orlické Hory, an artillery bunker stands empty — the guns the Munich Agreement left unbuilt. The museum wanted visitors to feel the weapon that should have stood there.

Phone AR couldn't carry it. This had to be **shared**: something a guide and a whole room live through together, at a scale and volume only a real projection delivers.

## The Approach

### A life-size hologram you switch on and fire.

We rebuilt the **Škoda 10cm vz.38 howitzer** — one of three meant to hold the line — as a rear-projection hologram driven by a **PS5 controller**. Switch it on and the room changes: a war soundscape rises, the lights drop, the projection ignites. The guide explains the machine, then lets visitors fire it.

To make the scale real, we printed a **rectified orthophoto** from historical aerial photographs, showing the nearly **12 km** the gun could reach.

## The Impact

### A shared moment no headset can give.

Visitors don't hold up a phone — they stand together as the bunker comes alive, a collective experience only a true-scale projection can create.
