Open Look scrollbars would be impossible to implement properly in the web browser without using the Pointer Lock API that let you "warp" the mouse cursor position, because when you click on the elevator or cable, the elevator cab actually pushes the cursor up and down with it.

Here's a demo of Open Look scrollbars from Brad Myers' "All The Widgets" video, which he produced for the ACM CHI 1990 conference. It also has demos of many other kinds of scrollbars and other widgets. (Sun Microsystems, Inc. OPEN LOOK, 1988):

When I was working on The NeWS Toolkit at Sun (an Open Look toolkit implemented in PostScript), Jonathan Payne implemented the Open Look scrollbars, and I thought they had such a cool interesting 3D shape with their elevator, cable, anchors, ridges and arrows, that I carved an 3D Open Look scrollbar for him out of soap as a birthday gift. (He also implemented JOVE: Jonathan's Own Version of Emacs for Unix, and JED: Jot EDitor for TNT.)

Google Wave also had elevator-like scrollbars with arrows on the elevator, but since they were implemented in the web browser without the Pointer Lock API, they could not push the cursor like Open Look scrollbars, so they implemented a weird shadow and didn't move the elevator until you moved the mouse away, with was very confusing to users:

>Using Google’s scrollbars, it’s also possible to scroll by clicking, but since the arrows are attached to the thumb, that creates a bit of a problem. Typically, the thumb indicates the scroll position. But since you can’t move the thumb while the user is clicking on it, Google has introduced a second element, a «shadow» that is displayed below the thumb. This shadow indicates the current scroll position:

>If the user moves the mouse away, the thumb will eventually move to the shadow.

>I did not notice this until a commenter on Hacker News pointed it out. He also notes that the scrollbars seem to perform poorly with longer waves.

>The Non-Standard Wave Scrollbar

>Figure 6-1. Unlike the scrollbar in your web browser, Wave's scrollbar is the same height no matter how long the list it's scrolling, which keeps the up and down arrows always the same short distance away.

>The scrollbar on the right side of Wave's panels works a bit differently than the scrollbar in your web browser. Like most scrollbars, you can drag it up and down to scroll, or click its up and down arrows to move it. Unlike most scrollbars, the Wave scrollbar's height doesn't change. It's always the same, small size, which puts its up and down arrows in close proximity to one another, as shown in Figure 6-1. Google's intention is to benefit people accessing Wave on mobile devices or netbooks with a limited mousing area, but it has thrown off some preview users.[2] Google explains "the deal" with the scrollbar in Wave's Help section:[3]

>You might find that the scrollbar in Google Wave behaves a little differently from scrollbars in other Google products. To use it, you can drag the bar or you can use the arrows on either end of it—clicking the arrows without moving your mouse allows you to very quickly scroll up and down the page.

>Even at this early stage, at least one developer has created a Google Chrome extension that reverts Wave's custom scrollbars to Chrome's native scrollbars.
