Prague-based artists Vojtěch Fröhlich, Ondřej Mladý, Jan Šimánek, and Vladimír Turner transformed a rotating billboard into a carnival-style attraction during a recent guerrilla art maneuver, Kolotoč (Merry-Go-Round). The group climbed to the top of the massive advertising board that slowly rotates above a busy street, via its maintenance ladder. After securing cables to the scaffolding the artists lowered themselves down through the air seated on a type of wooden swing. The whimsical contraption allowed the billboard to move them around in circles. Check it out in action past the break.
