Q: What are your opinions about how the public in general, and many artists, have difficulties discerning between what is artistic in abstract paintings and artistic in abstract sculpture? Why do 2D and 3D differ?
A: If you're talking about 3d in abstract paintings the closest would be those pictures your have to look at cross-eyed.
I think that's where public may get confused. A 3D sculpture on the other hand is obviously 3D to everyone.
