"Spirograph" (2015-05-19)
(move cursor / orient device to shape a nice effect,
press anywhere to cycle through display modes)

Play with this generator of spirals, experiment the different particles effects. You may discover some strange blooms or stars or imaginative things ^^

I built this toy while I was doing some research on some animated particles behaviours. I need an optimised rendering, with an attractive effect

In this experiment, I use a geometric transformation similar to the "Spirograph" drawing toy from my childhood ^^ I set a cool range of parameters, and tried some rendering effects / modes

At last, I can draw some nice spirals in no time !

I take my revenge on my dear old "Spirograph" toy :p :) <3
