My idea of variable scales is not worked out in any way. I guess, with a smaller scale, things happen much faster on the screen and therefore we all need supercomputers or we accept slow motion shows, so, it´s just an idea. Changing some physical parameters while changing the scale should not be too hard for CL.

Also, I would like to see wind factoring into my bridge building, areodynamics can play a very large roll in bridge design.
