Andrew Novinc has created a Space: 1999 virtual reality experience. It includes some of the exterior and interior Eagle and Moonbase Alpha sets such as Main Mission, Koenig's office, Season 1 corridor and travel tube. You can pick up and examine certain objects including the Eagle, commlock, stun gun and room dioramas. You can change the gravity to see how things fall on the moon, and show screenshots to compare the VR model with the actual studio sets.
There are additional views by Andrew in the Command Office guide, Main Mission guide, Travel Tube guide and Computer Room guide.
