"Art" is the arrangement or re-arrangement of articles, natural or made, into a form that has no intrinsic use or purpose other than as decoration.
Both the furniture and the boxes [...]are meant to be pleasing to the eye.

I also don't agree that all art should have no other use other than decoration, however, what both of these statements seem to agree on is that art should be 'pleasing to the eye,' or at least move us in some way. It is true that there is no accounting for taste, but I fail to see how anyone can be move by a lightbulb turning on and off every few seconds... I sure some will disagree with me on this one!

If the world doesn't suck, we'd all fall off.
