It's a digital art using my custom noise function.
The digital art of the animation using my custom noise.
This is the creative coding animation. I wrote the code in the 'Processing' programming language. It creates a digital art animation of the pulsating flower.
It's a remodeled version of 'Interstellar Overdrive'. When I looked at the source code of 'Interstellar Overdrive' again, I felt it is terrible, and I wanted to recreate it. I simplified the code and made another animation work.
At first, I made this spiral figure.
And I felt something lacking. So I added this background image. These three curves like vine are from 'Heard It Through The Grapevine'.
An example source code of the 'Processing'.
This code does not display any images on the screen but generates image files in frames directory. You can make an animation with these files.
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.

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.
