This was an installation at Mediaruimte, Brussels in 2004, a simulation of a cyclic universe. Every frame 10000 new moving particles are added so that after several ten thousand "years" (1 rotation = 1 year) the space ended up as white cube, fully saturated with matter. Due to the way this cyclic nature has been coded it too created the paradoxical situation where the simulation never actually slows down even though the number of moving particles is approaching infinity. The lines are a visualization of the invisible moving attractors in that space and the inverse square law used to compute the particles trajectories. More info: toxi.co.uk/p5/ideaspace

    at 1:30 . you have the particle breaching out the array bound and it makes these white straight lines before the screen. Usually it crashes after this.

    How can you generate so many partiles whithout it crashing ?

    the straight white lines are due to the lack of Z clipping in the old version of Processing and occur once a particle moves "behind" the camera and everything gets warped... the particles currently drawn are *always* just limited to 10000. however am using 128 offscreen buffers which store and accumulate the animated history. so visually the universe acquires more and more particles over time, but CPU load remains constant...

    here's another example using this technique: toxi.co.uk/p5/cyclo/
