Just thought i'd post up some images of how the design for the bridge and various other parts came about.
This is the final model with the textures and lighting being placed. The over theme of the structure is one where the boundaries are being crossed. Gravity is being defied and additional to this the structure is on the side of the cliff to emphasis that as a race we are evolving rapidly and growing in numbers. For this reason space is becoming a very valued thing. In the future it might be possible to use space is this way where we are building ontop of and to the side of existing structures.
