"Ideas can be works of art; they are in a chain of development that may eventually find some form. All ideas need not be made physical.

Ideas do not necessarily proceed in logical order. They may set one off in unexpected directions, but an idea must necessarily be completed in the mind before the next one is formed.

For each work of art that becomes physical there are many variations that do not.

A work of art may be understood as a conductor from the artist's mind to the viewer's. But it may never reach the viewer, or it may never leave the artist's mind."
- Sol LeWitt
