Pixel bender comes with a pixelate filter sample from Adobe which is written very carelessly to say the least.
I’ve tried creating a better version of that shader using a smarter sampling algorithm.
The filter can be downloaded here

demo:

I just finished writing the Zagat Survey Photo Contest, and the last thing I had to deal with was the facebook share button seemed to be broken, well no in real browsers just in IE, to make an annoying story short – I found out the share popup was actually working it was just hiding BEHIND the main flash component, which for performance reasons was set to wmode=”window”

So remember,  IE+FLASH+FB:SHARE = display:’popup’

The full share code:

var share = {
 
	method: 'stream.publish',
	display:'popup',
	message: 'Upload a photo for your chance to win a trip for two to Wynn Las Vegas!',
	attachment: {
		name: 'Zagat Survey',
		caption: 'Zagat Survey Photo Contest',
		description: (
			'Take a picture of a anything that says Zagat, easily upload it by visiting zagatphotos.com and you could win The Ultimate Getaway for two at Wynn Las Vegas!'
		),
		href: 'http://www.zagatphotos.com',
		media:[{type: 'image', src: 'http://www.zagatphotos.com/images/logo.jpg', href: "http://www.zagatphotos.com"}]
	},
	action_links: [
		{ text: 'Join contest', href: 'http://www.zagatphotos.com/' }
	],
	user_message_prompt: 'win a trip for two to Wynn Las Vegas!'
};
 
	FB.ui(share, function(response) {console.log(response)});

I’ve always managed to avoid using Pixel Bender even though everybody around me (well not everybody just the super geeks) said it was exactly what I need.
I love the combination of technology and arts and Pixel Bender kind of lets you have fun with both and pretty fast too.
so I’ve been playing with it a little today and finally got this little cool tv noise effect (or kernel*) going.
