Confusion.

About this creative coding work.

This creative coding work was made with Processing.


I wanted to make a cloud chamber. And I failed as always. XP
But it grows beautiful and I love this. I love to play with glowing wire!

Processing example code (Java).

Please feel free to use it, if you like it.
To see other works based on my code is my pleasure. And my honor.
