After looking at this again (and I do not know why, but something just PULLED me into it) I think maybe one adjustment might look nice, the SHAKE text, I think it might look even better and mess with your eyes even more, if the letters in SHAKE overlapped adjacent squares a bit, so that the text is two toned (black AND white) does that make sense?
Well actually, I think the WHOLE IMAGE is Un-PC, but this isn't really about the message here is it? I mean, we are here for art's sake, not politics...so in that, if you wanted an image that makes your eyes cross and scramble, well I think you have accomplished that, MY eyes hurt now...that black and white image/text messes with my brain man....is it MY impression or is it true, that there is either a slight shadow on the black squares, or maybe a bevel or something going on there? Or is it maybe just the illusion?
