I have to admit, it took some time, but hey...  nice optical illusion

enjoy cats, running, bread, and a bit of w̶e̶b̶3̶ onchain data

lol, maybe it happens so quickly that i didn’t notice the first image

No but it’s what you see in the foreground vs in the background that changes. 
At first you’ll see the towel with the forks “embossed”, but then… and after that, your brain will not go back to the first image.

is there something more than 4 forks and a … towel?
