This is what is flickering away in the background; an algorithm from Ancient Greece to find prime numbers.
It changes each time you load the page so right now it could be psychedelic siezure inducing flashiness or it could be sitting there looking rather blank.
I love this algorithm, because, well who doesn't like prime numbers?
The story of this project is an example of trying to see something which can't be seen. I had known about prime numbers since I was a child but it wasn't until I read about this algorithm, where you list all the numbers you know, then starting with 2, cross off every multiple of 2, then go to 3 and cross off every multiple of 3 and so on. I though this would be a pretty interesting though laborious thing to do with painting. So I did it. It is actually quite interesting, though it doesn't sound fun I'll admit. The finished paintings can be colourful and lovely, but you don't see how the primes interact, dancing around one another, creating different patterns according to how the original grid is arranged.
I figured I could write a program to simulate the activity and you can see how the patterns form.
