Picture from 26.08.2016
Since 2012, the buildings for the international accelerator facility FAIR are being constructed. First, woodland was cleared, then the civil engineering started. In a few years, where once stood trees one of the world's most advanced basic research facility will be located.
There's a webcam taking pictures every 15 minutes. Based on these pictures FAIRprogress provides animated gifs for each day.
For the time being, all quarter-hourly pictures are archived as well as the animated gifs. Just check out the /images/ directory of this website and go through the listings. They are sorted by year/month/date.
A cronjob wgets the picture every 15 minutes. Every night, ImageMagick's convert produces a small, lossy gif animation as well as a big lossless one. (Do you have ideas for better looking configurations of convert? Just let me know.)
This website per default shows the small one. A click will display the big picture - but prepare for long loading time, the file is about 13.82 MB.
