This Processing sketch loads two images and creates an image mask that blends them together. The transparency of the image mask is determined by 4D Open Simplex Noise, which loops perfectly.

Expanding on last night's work with Open Simplex Noise. I figured the next logical step was to make a Minecraftian terrain generator, so here it is. If I ever felt compelled to build a game from the ground up, this would probably be my starting point.

So, I was on the hunt for a simpler way to make cool looped animations and stumbled upon this thing called 4D Simplex Noise. I found a super helpful tutorial on necessarydisorder's WordPress page called "Drawing from noise, and then making animated loopy GIFs from there". It was really informative, got me inspired, and had a spot-on title.
