It's a scroll bar with the contents wobbling as you scroll it. What am I missing, how is this useful?

It's a cool demo that's fun to play with. Cool demos like this can spark people's imaginations, that's how it's useful.

Earlier quoted context omitted.

Too late. Windows Phone uses similar "stretchiness" (but less cutesy) to indicate over-scroll. It cleverly presents an effect comparable to the rubber banding in iOS without, as far as I can tell, infringing Apple's patent. And yes, Microsoft has patented it.

I actually thought the WP thing was Microsoft cross licensing Apple's stuff (circa 1997 agreement), I don't get how it's any different from iOS. (I originally had an iphone and recently traded it in for a WP)... How is it different?

If you read the claims in Apples rubber banding patent, they specifically include "displaying an area beyond the edge of the document" (in iOS, the gray linen background) when you over scroll. Thus, instead of jarringly stopping at the edge without any indication that a boundary has been reached, the document keeps scrolling with your finger.

Windows Phone, however, does not show an "area beyond the edge" on over scrolling; instead, it anchors one edge of the document at the boundary, and subtly "stretches" the rest of the document to follow your finger. The effect is like trying to pull down an elastic sheet of paper. This indicates that the boundary has been reached, but without showing a separate "area beyond the edge". As such, it achieves an effect as intuitive as iOS's, but without infringing the claims.

(Yes, you really have to be the pedantic when evaluating claims.)

I'm pretty sure this effect came about because Microsoft wanted to work around the Apple patent. However, some sort of cross license, if not the one from the 90s, is apparently in place as well. Some UI elements in WP do infringe other Apple patents, such as the "disappearing scroll bar" one.

Thanks for the explanation.

I wish they'd cross license the Universal search thing, it'd be really nice because there's a dedicated search button on every phone.

This is neat, but really disappointing that there is no feedback when you're at the top/bottom and try to scroll further. It'd be so natural to have this bouncy effect happen in-place to let you know you've reached the end.

Booo this man. Its 'really disappointing' seeing someone complain about amazing free open code they're able to contribute to. Its great to offer feedback but you can do so without implying some sort of entitlement. Come on now...

Well I don't really found it useful. Ok, it's cute; I will give you this, but...

I have used different desktops and I have used every bell & whistle available. And I have really enjoyed them, sure, but just for three or four days.

I think there's a lot of movement in that scroll, it's battery consuming, and it just doesn't provide any help for the user.

But don't get me wrong, I think it's a nice project to test your design skills, keep up working =)

"really disappointing" ?? another example of the HN changes around here.

I think shurcooL's comment probably came across differently than s/he intended it. I think it was intended not as an expression of disapproval for the author, but rather as a description of how it feels as a user to scroll to the edge and not see it react in the satisfying way anticipated.

Interpreted that way, it's fine constructive feedback. But it's easy to see how it would be taken as a self-entitled complaint.
