The DHD.

To compliment the recently produced StarGate at Warminster Activity centre a DHD was added. This is not just a static prop though. The front symbols are all removable . The DHD features a sliding rear door which house the crystal tray. The crystals are removable. When placed in the crystal holders each crystal in turn lights up, red, green and blue. When all the crystals are in place the DHD outer ring lights up to show it is now active. This state makes the centre button active. When pressed by the player a siren sounds to indicate the gate is now active and open. At the same time the Stargate now lights up, powered from the DHD.
