The poster says, "Randomness is a gift from the cosmos"

I tried to convey three messages:

1. Everything in this universe is random just like a coin toss. Future is not pre-determined. I could never have predicted what the poster would look like before it was done because the outcome is always random.

2. The poster looks too complex at first. If you start by focusing on the complex things first you will not be able to solve anything. But if you just take it simply (in this case, by reading the sentence) you will find the answer. You would know that its not complex or anything. Its just random. Seemingly complex things are the most simple ones, just like the cosmos itself

3. The poster does not actually mean anything. The shapes are truly random but it doesn't really matter because, not having a purpose is a purpose by itself.
