Hammerwerk consists of four air drums woth eight pneumatically powered hammers for
which the stretched membranes of kevlar -a synthetic fiber of high tensile
strength- over a circular mounting with an internal diameter of 1.50 meters.
Attached to each drum are sixteen hammers each of which are fitted with a
pneumatically operated rotational joint the heads of which covered with
various materials, strike the membrane. The flaming orange color of the
membranes with their small insectile hammer arms gives Hammerwork,
especially when in movement, the appearance of a delicate, organic being.
