The comparison to children playing with blocks makes me wonder: If you spent long enough playing with these 4D toys, would you develop a deeper intuition for the 4th dimensional shape of the objects?

I've played with some programs I made to explore 4D objects, and, yes, you do gain some intuition.

Interestingly, I was told one of George Boole's daughters got lessons from a guy on 4D objects by using colored wooden blocks. She really picked it up, and later in life mathematicians would consult her about intersections of 4D polytopes.

If you haven't read Mimsy Were the Borogroves, you should.

That would be a perfect application of VR.

I’m sure most of us could learn a visceral understanding of 4D if we could push and twist 4D objects.

Sort of, but not really. The problem is you don't have sufficient information to know what should happen.
