Rob and Lotte asked everyone to smile more, also at strangers. That really moved me. I generally do smile a lot, also at strangers, and then I see them lighting up. I remembered an old poem I read - the one you see next to the picture, and came up with the idea of making a script that would fetch a random smile from <a href='http://www.flickr.com'>flickr.com</a>. The original idea was to make a mailinglist that would send out a fresh smile each morning. This way you would be reminded to smile today and spread some positive vibrations throughout the world. If there is a demand for it I will implement that feature. Or you can set it as the startpage in your browser ;-)<br /> <br />";
