DEMO is a hash cube that I spent nearly half a month researching，First, I drew a two-dimensional plane. Later, after consulting a large number of code explanations, I developed from 2D to 3D. This made me gain a lot and learned a lot of code knowledge I had never touched before. I'd like to share my learning experience with you.

Each side of the DEMO is different, and each DEMO is also controlled by the fxrand () function. Therefore, each DEMO is unique.

I agree with the webmaster that art is evolving.
