If you’ve done any  2D action game programming you may have had to go through the tedious process of going through a collection of 2D sprites and finding and recording vertex coordinates around the game objects.

It’s a major hassle to do this by hand, and for me personally it’s things like this that hold me back from doing things, or sometimes taking an easier way out (like using box collisions or spherical collisions just so I don’t have to do this), but it’s a fairly quick process selecting things graphically with this program

Fortunately Johannes Fahrenkrug has created a very nice time saving tool for getting these vertex locations, see this video of it in action:

As you can see it can even print out formats specifically for Box2D and Chipmunk which is great for Cocos2D fans.

You can download the source here on git: VertexHelper with a full Xcode project for easy compilation on your Mac (sorry windows users).
