Sol LeWitt

In my case, I used the elements of these simple forms - square, cube, line and color - to produce logical systems. Most of these systems were finite; that is, they were complete using all possible variations. This kept them simple.

And I think that still is true of this business - which is basically research and development - that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.

What I look for when I see a piece of art for the first time is some kind of emotional, intellectual experience, that's a combination of both of those things and is informed by my knowledge and something new that I see the artist doing.
