These are the QuickTime clips created entirely from still
pictures. The subject: the Silver SpringWave Pool Park, in
front of Silver Spring Metro Center #4 in Silver Spring,
Maryland. The Wave Pool is a kinetic sculpture patterned
after waves crashing against the Maine coastline. The photos
were taken with a Nikon 950 digital camera, at the rate of
two frames per second, on March 31, 2000. The camera was
mounted on a tripod; the photos are unaltered in any way,
and imported directly into QuickTime Pro (see
article for details).

on end (portrait mode), were imported at the wrong frame
rate, 15 images a second instead of two images a second. The
clip was reduced to half size (which is actually one quarter
sized) and saved with the CinePak codec. This (accidentally)
illustrates the excellent wave characteristics of the Wave
Pool.
