NTFS Streams
http://technet.microsoft.com/en-us/sysinternals/bb897440.aspx

The NTFS file system provides applications the ability to create alternate data streams of information. By default, all data is stored in a file's main unnamed data stream, but by using the syntax 'file:stream', you are able to read and write to alternates. Not all applications are written to access alternate streams, but you can demonstrate streams very simply. First, change to a directory on a NTFS drive from within a command prompt. Next, type 'echo hello > test:stream'. You've just created a stream named 'stream' that is associated with the file 'test'. Note that when you look at the size of test it is reported as 0, and the file looks empty when opened in any text editor. To see your stream enter 'more < test:stream' (the type command doesn't accept stream syntax so you have to use more).

rocket dock
http://rocketdock.com

Have you ever glanced over the shoulder of a Mac user and seen the nifty little bar of icons at the bottom of their screen? This is known as a "dock." For those of you that haven't seen this, a dock is simply a bar that can be set to the edge of your screen with a background and a row of shortcut icons. The function of a dock is to bring quick access to these shortcuts in an organized fashion relieving your desktop of clutter. It acts much like the Quick Launch, pointing each icon to the original folder or file.

Note: RocketDock does not remove, replace, store, duplicate, or backup any of the items you drag into the dock. You should never delete the original items. Dock shortcuts are not stored as files and cannot be dragged back onto the desktop or anywhere else.
