Hidden Optical Design

I usually browse the first page of FFFFOUND! for a dose of visual inspiration each day.

I saw these awesome optical illusion/designs that look like a field of dots or lines. It appears they are album sleeves for a band called Soulwax.

I would have passed right by it, but I usually stare at optical designs for at least a few seconds to observe what prolonged visual effects there are. As I was looking at it I must've briefly blurred my eyes, because I was surprised to see words appear for a second. This is a pretty crazy effect that can be seen a few different ways:

• squint your eyes
• make your vision blurry by ''flexing' your eyes
• cross your eyes just a little bit
• raise your eyebrows & stretch your eyes tight
• you get the idea

I think these are perfect examples of the ephemeral nature of language & ideas...
