This pattern are animated rings in a hexagonal grid with neon colors.
Nice work! I have notice that all these GLSL effect are published in GLSL Sandbox web site with source code. May I know are we allow to use the source code in our own project? Thanks!
You can use and modify the code, if you link to its origin.
If you enhance the code, it would be nice to fork it at the GLSL Sandbox and save it, so that everybody can learn from it.
