Heinz Mack, co-founder of ZERO, early on placed the emphasis of his work on vibration, oscillation and serial structure.
"I think that lines condense into an energy field, a structure in which all of the parts, all of the elements, relate to each other in an indissoluble context, and begin to oscillate or even vibrate when we observe them with sensitivity, calm, and disinterested interest." Heinz Mack
