It looks like the lines bend the wrong way. I would expect everything to bend down when I scroll up, but it does the opposite. Very strange.

It's to match where your finger would be when scrolling. On a touch device/mouse using natural scrolling it would go the direction you expect. Using traditional/inverse scrolling does the opposite.

There is a control in the top right corner that lets you change which way the lines bend.

edit: This does not show up in IE
