Pillow Fight Madness
Thousands of spectators watched hundreds, if not a thousand or more, students do battle on Saturday in Cracow's Rynek.
Fighting in a style best known as freestyle (or in some cases huddled in submission), the feathered pugilists carried on with glee as tourists and onlookers snapped photos and took videos.
