This incident has not been tested in court, but it highlights a potentially disturbing practice. In July 2016, German computer magazine LinuxUser reports that a German blogger Christoph Langner used two CC-BY licensed photographs from Berlin photographer Dennis Skley on his private blog . Langner duly mentioned the author and the license and added a link to the original. Langner was later contacted by the Verband zum Schutz geistigen Eigentums im Internet (VGSE) (Association for the Protection of Intellectual Property in the Internet) with a demand for €2300 for failing to provide the full name of the work, the full name of the author, the license text, and a source link, as is apparently required by the fine print in the license. Of this sum, €40 goes to the photographer and remainder is retained by VGSE.  
Incubation is a temporary break from creative problem solving that can result in insight.  There has been some empirical research looking at whether, as the concept of "incubation" in Wallas' model implies, a period of interruption or rest from a problem may aid creative problem-solving. Ward  lists various hypotheses that have been advanced to explain why incubation may aid creative problem-solving, and notes how some empirical evidence is consistent with the hypothesis that incubation aids creative problem-solving in that it enables "forgetting" of misleading clues. Absence of incubation may lead the problem solver to become fixated on inappropriate strategies of solving the problem.  This work disputes the earlier hypothesis that creative solutions to problems arise mysteriously from the unconscious mind while the conscious mind is occupied on other tasks.  This earlier hypothesis is discussed in Csikszentmihalyi 's five phase model of the creative process which describes incubation as a time that your unconscious takes over. This allows for unique connections to be made without your consciousness trying to make logical order out of the problem.
