I wasn't going to get this set, I just deemed it too big and in too much need of extra stuff to complete it.
But demand was there for Cardboard Galaxy to do some of the "extra stuff" for my customers, so I bought one as a business expense and started making inserts to slip up under the main platform to bring the wall of it all the way down to the floor. People seem to like them enough, and with some lining on the back of my inserts (one guy used tinfoil to great effect) they contain the light you might put underneath to get the orange glow.
I just bought a second set (from amazon on sale currently) to finish the circle and see what I can do to work up a backdrop or mini-scenes for under the back gantry pieces.
At the end of the day I think it is a neat set, especially if you are messing around with lighting it and taking pictures with it.
