The U.S. Geological Survey in Menlo Park hosted an Open House, June 2 - 4, 2006.
At the USGS Open House,
a very popular interactive activity is "Dress Like a Marine Geologist."
Participants don maritime field attire and are video captured against a green screen background.
Using a chroma key unit, an "at sea" scene replaces the background.
The image is placed on the web.
