observations of the other universe

I live in two worlds, I've gone over it before, and will expand on it in the future.

Something that just came to mind as I was looking at Art this morning.

Differences in how the two worlds approach art.

Default World 

2d art rules 

4d is making huge strides towards being validated as real art 

interactivity refers to how "readers" approach it 

TTITD world (that thing in the desert), and including the regional I attend 

3d art rules

4d is breaking in but...
        if it requires a projector, still 2d, not considered for grants
        if it requires a 'stage', performance is considered folly, not considered for grants 

interactivity refers to how "readers" make it function

Discuss.
