counting sheep in processing

Nikolaus Gradwohl2009-04-21T04:23:00+02:00

Computer are very well suited for boring and repetitive work. I can't imagine anything more repetetive and boring than counting sheep. so i made a processing sketch that does it for me.

processing bubbles

Nikolaus Gradwohl2009-04-13T21:44:00+02:00

here comes another completly useless processing sketch by me this time starring bubbles

ok, it's not that useless i changed the transparency of the bubbles according to the speed so slower bubbles seem to be more distant from the viewer than faster ones.

this generates a nice and simple parallax effect.

Digital Caleidoscop

Nikolaus Gradwohl2009-04-09T05:58:00+02:00

i made a digital caleidoscop using processing sketch click here to see it in action. I had to use openGL for this sketch so i'm not sure if it works as an applet on all plattforms. Download the code and run it as an app if the applet doesn't show anything.

i made a processing-sketch showing a blooming tree

every time the applet is started it grows it unique tree

how to detect presentmode in processing

Nikolaus Gradwohl2009-03-15T10:21:00+01:00

in processing sketches can be run in "present" mode. which means a frame is generated in fullscreen mode and the code of the sketch is centered on the screen.

to change the size of the actual sketch depending on wether presend mode is active or not
the following code can be used

void setup() {
    for ( int i = 0; i < args.length; i ++ ) {
      if ("--present".equals(args[i])) {
        present = true;
    if (present) {
      size(screen.width,screen.height, OPENGL);
    } else {
      size(600,600, OPENGL);

    // do your normal setup stuff here
