I love this feeling of the stroke of a pen.

Description of this generative artwork.

It's a generative artwork made with the 'Processing' (Java programming language).

It was made with the same idea of Let's Twist Again. It's a kind of complex Lissajous figure I think. It looks good in still image but not in animation. 

I love this feeling of the stroke of a pen.

 

The 'Processing' code example.

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.
