Avgrund is a modal concept which aims to give a sense of depth between the page and modal layers. Uses CSS transforms to scale components and CSS filters to blur the page. Built for the fun of it, not intended for any practical use.
Vague.js is an experimental script that allows you to blur any kind of html element. Vague.js checks if the user’s device supports the CSS filters otherwise it can fallback using the SVG filters or the Microsoft css filters.
tiltShift.js is a jQuery plugin that uses the CSS3 image filters to replicate the tilt-shift effect. This is a proof of concept and currently only works in Chrome & Safari 6
