Here's a video I found of the flickering: https://www.youtube.com/watch?v=MbIe0iUtelQ https://www.youtube.com/watch?v=MbIe0iUtelQ According to the video description the windmill is 1000 feet (304 m) away, and is 40 stories (132 m) tall. FWIW in Denmark windmills have to be at a distance from nearest (inhabited) building by least 4 times the height of the windmill (source: http://naturstyrelsen.dk/planlaegning/planlaegning-i-det-aabne-land/vindmoeller/afstandskort/ http://naturstyrelsen.dk/planlaegning/planlaegning-i-det-aab...). This article <http://www.windpower.org/da/energipolitik_og_planlaegning/nabo_til_en_vindmoelle/skyggekast.html> http://www.windpower.org/da/energipolitik_og_planlaegning/na... says that the windmills can cause shadows for up to 4-6 weeks a year. It is computed when this will happen and the windmills can be stopped for that period, although the law doesn't mention this. I linked the Danish sources. You might want to put it through google translate.
