Once there was a time I participated in a design competition. Unfortunately I got to know about its existence in about 3 days before its ending. The task was to come up with the idea of how to make people interested in reading books again. Welp... Three days have passed like one and I uploaded my project at the last minute of the last day (precisely at 23:59). 

I didn't win anything but I really enjoyed the experience and had a very nice feedback from the jury. :)
