An installation to get some action into the frame is these days usually remotely, inserting some 3d rendered elements in to video footage. However if interaction with the elements should take plae it is getting more complicated and a straight forward option to do it is to go with a stop motion animation. This way it is possible to aso controle the crowd interaction with the animation.
Möbius is a stop motion sculpture by Melbourne on Federation Square. It is built from twenty-one large triangles that were alternated for each shot. MÖBIUS is a sculpture that can be configured into many cyclical patterns and behave as though it is eating itself, whilst sinking into the ground. The result is an optical illusion and a time-lapse of people interacting with the sculpture and moving through Melbourne's landmark location throughout the day.
