This witty bookmarklet simulates the effect of looking at your site while inebriated. It uses JavaScript to seesaw any web page back and forth and slightly blurs the text, recreating with reasonable accuracy a feeling that will be familiar to many of you reading this right now. It claims to give designers and developers “insight into how users actually experience interfaces”—implying, I suppose, that there is a lot of under-reported browsing while boozing happening out there.
