I have sworn to master the pen tool before moving on to try any other form of Photoshop.
...basically, I'll never try CS3 out.

Aww, lol. Ask me if you need any help. :D Having attempted many times to make vexels, I've gotten used to it.
I'm really looking forward to the the automatic layer alignment and blending tools.

Using automatic layer alignment and blending, easily combine the best parts of multiple images of the same scene into one "best" image. Simply place multiple, related images on separate layers in one document, and let Photoshop CS3 analyze the contents, moving and rotating the layers so they overlap as precisely as possible. Then use the masking tools to reveal the areas you need from different layers to finalize the elements of the composite image. Automatic layer blending seamlessly blends the color and shading into the final image. The "Auto-Align Layers" and "Auto-Blend Layers" commands are both found in the Edit menu. Note that you must have multiple layers selected simultaneously in the Layers palette before you can apply these commands.
