CC wrote me that he was trying out these two apps to compare against the Windows Vista Aero navigation tools such as Windows Flip and Taskbar Thumbnails.
Software comparison from CC:
For some reason the freeware sites have been pushing these two applications, so I decided to compare these two against the similar Aero features in Vista.
RocketDock and ThumbWin: They both do the same thing but ThumbWin is better looking and adjustable in many ways so ThumbWin it is. Tested on Vista OS. Dragging a thumbnail to any position is available.
ThumbWin uses low resources with 568KB used compared to Aero at 7.2MB. All the thumbnails pop up but on Aero's thumbnail you can only see one at a time.
Rocketdock's thumbnails are not movable and it uses 4000KB.

Quote from a review at Cybernet News:
The best way to demonstrate the features of ThumbWin is with a video, so before you head on over and get it setup checkout what it really has to offer.
