Cloud pictures & timelapses

Please, feel free to post your weather pictures, clouds and timelapses made during (or after) the summer school. A timelapse manual from Martin Setvak (Czech Republic) is available at: http://www.setvak.cz/timelapse/timelapse.html

You can already find one example from the 2014 summer school:  a convective gust front taken from the balcony of the Alfredo Hotel.
