Here is the set I have designed for BB8 eviction interviews:
It is based on the test card eye in 3D. A semi-circle in the middle is raised to the same level for the interviews themselves (the keyhole shape is at the same height too), with the black and grey blocks on the right hand side acting as steps up to it. The other segments are raised at random levels.
There is 1 giant screen in the background with 3D coloured blocks around it.
What do you think? (Screenshots from different angles available on request)
