This is one of my favorite shaders that I’ve made. The sense of forward movement, sandwiched between two digital planes of coloured energy. The shapeshifting monolith, reflecting the glowing planes with its flat, coplanar faces. The way it switches between big and small, orthogonal and diagonal. And it glows and I love things that glow. And the name is really cool. Good job, past me!

I made this shortly after seeing Squarepusher at the 2015 Brighton Festival, wanting to replicate (parts of) the effect seen in the video below.

Warning: Flashing imagery.

Source code below the fold. One thing I remember about it is that the grid function is what creates the pattern on the ‘walls’ and that I at one point revisited the code and was unable to figure out how that function actually worked. I expect no further success were I to try understanding it today.
