I created upper and lower deck mockups to check for three things:
- How the physical structure impacts the room
- Sight lines into the upper and lower scenes
- "Reach in" distances

The mock ups are formed from three pieces of 30"x40" foam core poster board. In this photo, one deck mock up completed, a second ready is ready to be cut.
The decks were cut to a 44" radius to accommodate a 40" track radius.
