What determines the most complex thing that you can visualize and manipulate in your minds eye?
For example, I can visualize, rotate, and manipulate molecules in my mind's eye... but only up to 4 atoms. Sure, I can imagine things much more complex than that. I just can't "see" them in their entire complexity at once. So, here is my question: what is the most complicated thing YOU can visualize and rotate in your mind's eye and what do you think determines the level of complexity you can "see"?
