The line at the end had me thinking:
Does it perhaps make sense to call us 5D artists?

2D: photography and painting.
3D: sculpting.
4D: film, live performance, and 3D animation (adding time as the fourth dimension).
5D: games (adding variations in the timeline [that is, interactivity] as the fifth dimension).

Just as a performance could be expressed as a single 4-dimensional object, every different experience of a game could be expressed in a single 5-dimensional object, with the fifth dimension filling out as you look along the fourth dimension (the beginning state is always the same, but as time goes on the possible different states of the game increases).
