close-up timelapse video: freeze point in gras at night and a visiting slug

At the beginning of the video the temperature is about 2 celsius, at the end -0.5 celsius. At 20s the temperature turns negative, as can be seen by the reaction of the gras and the water on the gras is freezing (unfortunately, both effects are rather faint). By chance, I even got a slug on my video, which runs for cover when it's about to start to freeze.

Footage taken with a "Pentax Optio WG-1 GPS" in 45s interval mode. The approx. 1000 pictures were processed with the help of "ImageMagick" and "ffmpeg".
