In this stunning black and white photograph we see a man feeding birds in Krakow, Poland. The contrast is mesmerizing and strangely reminiscent of an yin yang symbol or even a ‘spy vs spy’ comic. According to commentor genjew, this is a walking path by the Vistula river that winds through the city.

The image has gone viral online, amassing over 4400 net upvotes on Reddit (which is astronomical) and over 4,500 likes and 2,500 shares on Facebook as well.
