A small update to lbear's QR Scanner. Very good idea of his to explain how to use these codes! Basically, the changes were:

1. the screen image is in perspective now
2. a wider red scan line
3. changed the yellow 'light' to red as to associate more easily to a bar code scanner
4. changed the code linked to an URL. Now it shows the text message "OK!", just a kind of an easter egg.
