I wrote another "done in 10 minutes"-processing sketch for no particular reason

I wrote a little processing sketch to explore the vector arithmetic functions of the PVector class

I created a new set of pictures for my livingroom using a small processing script.

The script generates a pattern of circles and saves it as a pdf files each time a key is pressed

Processing Flowers for the livingroom

Nikolaus Gradwohl2013-10-16T10:03:48+00:00

I created another set of images to hang on my livingroom wall. Here is an example of the generated images and the code of the sketch I used

processing flowers

The code creates a petal with no stroke and an pastel fill color and then redraws the shape 3 times without a fill color.

processing blob

Nikolaus Gradwohl2013-09-26T04:04:47+00:00

this sketch creates an animated blob by drawing 10 bouncing ellipses with random sizes two times at slightly different sizes to create an effect that looks similar to metaballs or lava-lamps, but can be computed very fast and easy.

25-Minutes timer in processing

Nikolaus Gradwohl2013-09-20T05:13:51+00:00

I have written a small processing pomodoro timer. I used it to run on my Desktop but it should work in android- or javascript-mode too. you can download the pde file here if you want to use it too, to start a time slot just click on the sketch window.

neon lines in processing using a glsl filter

Nikolaus Gradwohl2013-08-19T07:47:18+00:00

I made a short processing script that draws sine curves and uses a glsl blur filter to add a neon effect


To create this effect you need a processing sketch drawing the curves and a glsl filter that adds the blur effect.

endless pattern generator

Nikolaus Gradwohl2013-08-12T06:20:38+00:00

Back in my Atari computing days I was fascinated by the endless pattern generators that generated never repeating complex patterns on my screen. This is a processing sketch that recreates this effect
