I had meant to take a time lapse, with incorrect output filename: ffmpeg -r:v 4800/1 -i joined-quiet.mp4 -r:v 4800/1 -i joined-quiet.mp4 -r:v 12/1 sped-up-400x.mp4

If you have a big monitor, I recommend full-screening. It's 1920x1080 pixels.

This is probably Oxalis triangularis; the seeds or roots happened to be present in the beginning of the timescales.

I had meant to take a series of time lapse photos, but accidentally took a 2 hour 18 minute video. The following was supposed to speed up the video was in 2 GB chunks in the `raw/` subdirectory, so I left it alone. Much better than the 16 GB source video in any event!
