The meaningless formula creates a significant mechanical drawing
Mechanical drawing with meaningless formula.
This is my creative coding artwork that draws significant mechanical design drawing. It's a by-product of my 'Above the Clouds'. The code was written in Processing.
I rethought the idea of making something with rim rectangles that I abandoned on 'Above the Clouds'.
I tuned the parameter to make an interesting pattern every run time.
float pattern = floor(random(1.0, 10.0)) + random(0.005, 0.010);
And I got into making a nice background image. I used two layers for the background and one layer for the foreground image this time.
Yet another implementation.
An animation that draws with 'blendmode(DIFFERENCE)'.
The 'Processing' example code.
Please feel free to use this example code under the terms of the GPL. To see other works based on my code is my pleasure. And my honor.
This code does not display any images on the screen but generates image files in frames directory.

To make something is my pleasure. Having fun in endless trial-and-error. Now, I'm loving creative coding and showing some example code in my blog. Mainly creating Processing code examples.
