"One of the most important developments
in the art of the 20th century
was the birth of the technique of collage.
It opened up a new world of perception
in which matter and spirit can have a new kind of relationship,
one never visualized before...
... Tillis has given voice to another way of seeing,
has visualized another way of being.
The experience of Tillis is joyous.
His motions are magically musical.
He actually dances the dance of it,
the dance of rapture."
