POPSMake collages from online photos Collagr.com gives users the ability to generate backgrounds from images they have stored in multiple places on the internet. They can then place that background image on their MySpace/YouTube/Break.com page. Right now they only support getting images from Flickr, but they are adding a lot more image sources and extra graphic editing functionality very soon.

POPSAre Aliens from other worlds here? Some part of this are interesting. In particular listen to Ronald Regan's speech to UN and what he says. It is somewhere around 22 minutes. Makes one think and also wish that an Alien race would land here and maybe help bring a stop to all the fighting on earth!

It's a wonderful example of original, multidisciplinary academic research bridging history and mathematics that happens to force us to re-think the sophistication of ancient geometrical knowledge. When Lu looked at photographs of Islamic buildings, he found that he could break the patterns on their surfaces up into the same shapes, even though the shapes often weren't immediately visible. "I couldn't sleep for days," he said. "I skipped Christmas break to work on it."
