That strange unlabeled port / blue cable is the "Interaction Port", new in Mac
OS 10.6.
It's a shortcut for moving objects on-screen using mouse-dragging. Without the
Interaction Port/Patch, you could recreate the same functionality using the
Mouse, Sample & Hold, and Math patches.
There's no documentation, just a paragraph in the release notes:
http://developer.apple.com/library/mac/#releasenotes/GraphicsImaging/RN-QuartzComposer/_index.html
>> The new Interaction patch allows access to interaction data from Sprites,
>> Billboards and Mesh Renderers. These objects can be interacted with directly
>> or used as placeholder objects when interacting with other objects. To
>> access interaction data, connect an Interaction patch’s interaction port to
>> a Sprite, Billboard or Mesh Renderer’s interaction port. Then, connect the
>> desired output ports of the Interaction patch to either the associated ports
>> on the connected Renderer to control it directly or elsewhere within the
>> composition.
