So I decided that I really miss having landscape email on my Pre2, and decided I would get the landscape email patch updated for webOS 2.0.1. Poking around inside the email app, I saw a strange picture in the images folder.
I have been teaching myself how to write apps for webOS, so I was familiar with the app structure. I dug around the controllers folder, and found out how to trigger this image to appear.
Send yourself an email with the subject "supercowpowers" without quotes. When you open this email on your device, you will see three cows cascade down your screen over and over.
I got a good laugh out of this. Sorry all you 1.4.5 guys, this easter egg is only in 2.0. If the carriers ever release it to yall then you can see it. The thing I really feel good about is I found this easter egg before the webos-internals guys did. Just joking around, I am thankful for everything I have learned from those guys.
