I was asked if I could take a time-lapse of plant stomata opening and closing. "Probably not" was my answer, at least probably well than the ones on Youtube.
Something which struck me as I was stooging around, was this fellow's work.
For me "good in parts" applies, but the good, is worth looking at:

I have a purple-leaved tradescantia to look at, but looking will probably be all.
