Sweepers Clock

Maarten Baas combines theater, art, film, and design in Sweeper's Clock to make a 12-hour-long movie in which two performers replicate an analog clock by sweeping two piles of garbage (one for the hour hand, one for the minute hand) to indicate the time.


Scrapple is an audiovisual installation in which everyday objects placed on a table are interpreted as sound-producing marks in an "active score." Scrapple works as a simple form of augmented reality: the system scans the table surface as if it were a kind of music notation, producing a four-second music loop in real time from any objects lying there. The installation makes use of a variety of playful forms; in particular, long, flexible curves allow for the creation of variable melodies, while an assemblage of cloth shapes and small objects yield ever-changing rhythms.

Moving Objects

Captured inside a large round window, hundreds of black rings travel randomly left and right along more than fifty horizontal strings. Closer examination reveals that the strings are driven at each end by small motors and that the rings that seem to pass through each other are actually bouncing against one another. Moving Objects is a site-specific piece partially supported by SwissNex San Francisco.

Simply Smashing

Cummins has created a site-specific version of her 2000 installation for the main entrance wall of the Exploratorium. A twenty-foot-long wall of approximately 900 water-filled wine glasses become optical devices turning the world upside down. Simply Smashing is an elegant and playful meditation on perception and fragility.

Machine with Concrete

Legendary kinetic and mechanical sculptor Arthur Ganson has lent us one of his simplest and most potent works. A motor is connected to a block of concrete via a simple system of gears. The final gear, embedded in concrete, is set up to make one revolution once every 13.7 billion years, yet the machine whirs uninterrupted.
