SpritePlayground is a simple bit of Cocos2d-iPhone 1.0.1 exmaple code that shows you how to do
the following:
1. Create a "composite sprite" (a sprite made of multiple CCSprites with a parent CCNode)
2. Respond to touches
3. Rotate a sprite to face an arbitrary point on the screen
4. Instansiate a custom partical system (created via Particle Designer)
5. Use CCSequence and CCEase actions to move a sprite around the screen

This code is provided free and open source.
The sprite's graphic image is copyright John Pavley. All rights reserved.
(So just replace it with your own.)

Have fun
