Ten years ago or so Thomas Banchoff(sp?) of Brown University gave a presentation
at the Mineapolis Science Museum on the presentation of 4D solids.  They had a
vector (wire form only) graphics system that would ask for source (4D) and
presentation, (2D) and would work with standard solid shapes.  

He made films of rotating hyper-cubes about various axises and YES, I could
"see"  in 4d  {{ how do know i couldn't? }}

The frame of reference, line/square/cube/hyper-cube and the motion greatly 
helped in the comfort level of the seeing...

Please post any current references. Thanks.
