Concept: Playing with the back button

Howdy folks,

I've noticed a few people complaining about the back button on Android. I was hoping we could brainstorm a few ideas together and - hopefully - someone might take notice and implement something from our comments section.

So, to get the ball rolling, I spent ten minutes with Paint and a Google image search and came up with these rough ideas. I'm a secondary school teacher and this is my lunch break, so please don't bother complaining about thinks being a pixel out (although I did fix that odd pixel on the back button. WTH?). They take advantage of the way on-screen buttons can adapt for different purposes, just like they do when the keyboard is in view. It wouldn't work on devices without on-screen buttons, but I can't think of a good way around that off the top of my head.

Could be used to show when the button will exit the app into another app, as happens when you open a web page from Facebook etc.. I'm not sure if I like having the app icon there and I think it throws the bottom out of balance a bit.

The rest of the time it could look like current implementation. Not sure if I like the function of this one - but it does look more pretty I think.

Anyhows, has anyone else got any ideas? Do you know of any concepts already out there that are worth looking at?

Cheers folks,

P.S. I am stupid, so the images will probably come out giant or tiny or some other such helpful thing. I am sorry, but my next class is about to come in! Bye!
