In this internet-based earthwork, ground motion along the Hayward Fault in California is detected by a seismograph and transmitted continuously via the Internet to generate an evolving color field.

In 1997, Goldberg conceived of using a live seismic-data feed to activate an artwork he called mementomori. He met with colleagues at the UC Berkeley Seismological Lab to request access to the seismometer that continuously measures the Earth’s motion on the Hayward Fault.. With an economy of means and in monochrome, Goldberg transformed the seismic data into a live display that resembles the readings of an electrocardiogram—There are emotional memories connected to such an interface—sitting with a loved one at the hospital, watching the trace go up and down measuring the heart’s electrical activity. These are not necessarily happy memories. The title of the work is derived from the Latin phrase meaning, “Remember that you will die.” In art history, a memento mori is an artwork designed to remind the viewer of their mortality and of the shortness and fragility of human life.
Bloom incorporates the same seismic data as the mementomon . The mood of the piece was decidedly upbeat, exuberant, colorful and playful—replacing pessimism with optimism. The blooms resemble the representations of earthquake magnitude found on maps.
Bloom was commissioned in 2013 by the Nevada Museum of Art and is dedicated to Color Field painter Kenneth Noland (1924-2010)
