This is total bull. Or a cow. Or a male cow, with horns. It looks a little different than modern cows maybe, but that's because farmer animals are changing so fast. I saw a thing about farm chickens a 100 years ago compared to now, so different! Animals are getting fat and slow!

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.
