As Nirvana is a well-known chain of fitness centres in Beijing, the message could be very simple, as long as it was engaging. Double-rotating boards are now a common outdoor vehicle, but this is the first time both boards have been used to demonstrate a continuous movement in China.

We controlled the timing to have the rotating boards move back and forth every three seconds, simulating the up and down movement of a weight-training repetition. The Nirvana logo was placed on plastic and sat fixed, just above the glass holding the posters, in order to support the life-like visual trick.
