That dock - what were they thinking? I don't so much mean the solid tiles, more the way it worked - there was no cohesion at all to it. The interface he demoed there is one of the least coherent I've ever seen.
I can help you with that one... the system he is demoing is Mac OS X Developer Preview 3. This was the first time that the dock (in any form) had resurfaced at Apple since the first Rhapsody Developer Release. And even then, the dock was a stop gap measure until the Applications Menu was ready (in Rhapsody Developer Release 2).
At this point Apple wasn't sure what to do with the dock. They didn't want it to look like the NeXT dock (or even the Rhapsody dock), but they had to start some where.
The dock under goes a massive change in Developer Preview 4 (which came out later that month actually, my CD is dated May 2000). That dock stays pretty much unchanged until the release of Mac OS X v10.0 (the only noticeable changes I can see is the three dots that signified an active app was changed to a small triangle in the Public Beta).
Otherwise, the dock (very much like the aqua interface itself) was there to show off the new Quartz rendering. Almost all the
in your face features of Mac OS X Developer Preview 3 to Mac OS X v.10.1.5 have since been toned down quite a bit.
Things that were not part of the dock in DP3, DP4 or PB include dock menus for application or folders or docklings (which were only part of v10.0-10.1.5). Also the dock orientation was not an option, this was added first by third party developers who notice that the option existed in the system and later by Apple when they saw how popular it was.
One side note, on the Quake III test, that version was done with Carmack working with the Omni Group. It was made available for people with DP4 (and even PB as I recall), but after the release of v10.0 Id Software brought the development back inhouse. I don't recall the final Mac OS X version being ready before v10.0.4, and the Omni Group was asked to remove their version from their site after v10.0 was released.
And for those of you wondering, no... Quartz Composer does not work in any later versions of Mac OS X. And neither do any of the other cool apps included with the Developer Previews like HTMLEdit.
