This is a short clip from the 90-minute DVD "Exploring the Spectrum" by Dr. John Nash Ott.  Note the "exploringthespectrum" weblink is dead.  You can get the full video on DVD from here:  http://www.naturalenergyworks.net (scroll down, left side)
An exciting video journey through the world of time-lapse photography by one of the founders of the science of photobiology.  This is an introduction to Dr. Ott's time-lapse movies which show how plants and animals are deeply affected in movement, growth, form and sexual behavior by light-frequency (color) and low-level electromagnetic stimulation.

This video introduction and the larger DVD version were organized in cooperation with Dr. Ott by Dr. James DeMeo, who replicated some of Ott's experiments.  Dr. Ott passed away many years back, but you can keep track of Dr. DeMeo's research, publications and discussions through his OBRL-News Yahoo Group:
