Seven consecutive days during the growth and first bloom of a Lithops flower bud.

The opening/closing of the flower seems to be sunshine-activated. Since after the first two openings there was really bad weather for days, I had to stop the time lapse because the flower did not open again and I did not want to wear out my DSLR with 144 photos a day while nothing happening in front of the lens.

10 minutes per frame, 1034 frames total, 30 frames per second in the video. Taken with a Pentax K200D in aperture priority mode (f/32). Trigger: DIY 10-minute timer circuit connected to camera remote input. Camera power supply by wallplug adapter. Nighttime illumination by desktop lamp.

Successful uploading this video to flickr was pain, since flickr always gives you a "Bonk!" message after you have uploaded the whole file without success, not telling whether the codec was wrong or resolution, framerate or whatever.
