QuickBox2D pulley joint demo. This post is really meant to serve as part of the docs so it may seem a bit boring in its simplicity...
Have a look at the swf...

The link for:
QuickBox2D alpha 108
is not working.
Great site otherwise.

how do i apply friction to a pulley joint?
If I use the mouse and pull one box down, they kinda just keep moving. Is there a way to make them come to rest faster?
