You've probably seen cool time-lapse videos of sunflowers moving to track the sun. But do you have a sense of how fast they actually grow and move? It's surprisingly close to the limits of human perception.

I have a couple pots of wild yam, Dioscorea villosa. (Not an edible kind of yam.) It's surprisingly close to the limits of human perception.

I took a time lapse videos of plants as static objects, scenery. But they react with movement and growth, more chemical speech. They're living creatures, searching for juuust the right angle to catch one at it.
