Czech Artists Stage An Urban Intervention
The Prague-based artists in question are Vojtch Fröhlich, Ondej Mladý, Jan šimánek, and Vladmir Turner. Kolotoc translates to merry-go-round in English. Using nothing but ropes, climbing harnesses, wood planks and a massive rotating billboard on the side of a highway, they have created an urban amusement ride.
Turning a giant eye-sore (the sole purpose of which was to advertise to the masses) into a joyous carnival ride is quite an interesting visual. Check it out for yourself with this making-of video.
