At the moment of writing CSS Filters are only supported by -webkit browsers, so to be able to see the effects, please use Chrome or Safari! I have included all prefixes in each example, you never now when other browsers are going to support this, but for now they won't work ;).
On this page you will be able to see the different CSS filters which I used as experiment for the upcoming Daily Inspiration layout (ETA dec. 2012). They won't make it in the final version due to limited support, so I decided to show the effects here, on my personal website. On this tab you can play with the sliders to create your own effects. Keep in mind that if you use to many filters at once the browser may become very slow.
You can change the images if you want, simply click on an image, a pop-up will open showing you 4 images from my website and an input field. Click on any of the 4 images to change them, or enter a valid image url in the input field and when you hit submit the images will change.
