Hello! Move the cursor to the padlock in the URL bar! Click the padlock!
For the original, see Ben's amazing hack!
What's going on here?! As Ben's demo ^^ demonstrates, you can change the cursor to an arbitrary image (of size 128px by 128px). This image then escapes the viewport!! This is a boon for cursorjackers/clickjackers/other lovely people. I can convince you that this page is encrypted by putting a padlock in your URL bar! I can change the URL! As cool as this "escape the viewport" feature is, hopefully this page should demonstrate to the-browser-makers-that-be that it's not such a great idea for the poor old end-user ...
(p.s. looking for a job? Pusher is a lovely place to work!)
