Hi, glad you like it!

It is a classic demoscene effect, where you render the graphics to an offscreen buffer, and then either apply the image as a texture to a screen-sized rectangle that you repeat multiple times, alternatively create multiple scaled down versions of the image, which you then again blend together and display on a screen-sized rectangle.

Using the GLGraphics library is an easy way into working in this manner: users.design.ucla.edu/~acolubri/processing/glgraphics/home/

And for ideas, I recommend the following websites:
