I saw a theatrical performace in 1997, called The Peplum by theatre company Royal de Luxe.

It included ‘odorama’, a contraption that looked like a TV studio camera on dolly rails across the front of the stage, that sprayed the audience stands with about 6 different smells throughout the performance.

One of the smells was horse manure, which was a nervous shock for the audience. Yes it smelt like horse poo.

A very memorable performance, because of the smells, but also the exceptional company behind it.
