Chaos Machine at Cosmocaixa, Barcelona
The Chaos machine as I call it, can be found at Cosmocaixa Science Museum in Barcelona. Propelled into space by two powerful fans on the floor of the box, the balls simulate what could be the erratic movement of particles in an apparent disorder state, that is, chaos, although it is said that there is order inside this mess! Hmm, let's leave this to Maths geeks. I used autofocus in continuous mode to obtain these sort wormy shapes and added some violet overlay effect to make it more attractive.
