Circus Attractions

The word circus derives from the latin Circus κρίκος (krikos), meaning "circle" or "ring".That's why the performances in a circus usually take place in a giant tent having the shape of a wide circle from inside with hundreds of seats around it for the spectators.The colored lights hanging from the top of the tent provide a bright delighting atmosphere which makes the audience sitting at the edge of their seats already excited while waiting for the various shows.
In fact compared with the traditional circus, the contemporary circus tends to focus more attention on the aesthetic impact, character and story development,  the use of lighting design, original music, and costume design to convey the narrative content.
