Optical illusion: 'Mind of the Eye' Poster

I've been working on a optical illusion poster recently inspired from Bridget Riley's 'Current' painting. I must say it was difficult designing this because my eyes did tend to hurt while working on this but one of the reasons I wanted to create this poster was to break the rules of Legibility, overall I think it worked. What do you think?
