The generator is inside the code. The cube of random colors white to black is made from a fully custom random number generator. Info --> This is a high precision Linear Congruential Generator, it uses SUPER precise decimals to generate a number that is basically unpredicatable. If you were to try to predict the next number by brute force, it would roughly take around 1,000,000,000,000,000,000,000,000 seconds to correctly predict the next number
