Plants in motion

Roger Hangarter of IU has put together a wonderful site for time-lapse video of the movements of plants. We all know from elementary school about plant tropisms (e.g., phototropism, gravitropism). But I knew very little about nastic movements ("plant movements that occur in response to environmental stimuli but unlike tropic movements, the direction of the response is not dependent on the direction of the stimulus"). For example, the twining of morning glories or the "nutation" of sunflower seedlings.

It's easy to see why Hangarter's site has inspired art: Flower Play and boxtrio [beware: sound].

Wooooah... I was just looking at that site last week. I wish I could remember where I found the link, but it was referred to by someone who was very creeped out by it.

Synchronicity.
