Hordeling's back again <oh noes!>

I'm wondering where the best sources are for using sprites or the
particle system.

I thought I would start off with a simple effect, like having sparkles
fall from the mouse cursor.

The fire sprites in the demo seed did a lot of stuff with vertex lists
and Pyglet (Batch) that seem beyond what I need.

1. Is there an easier place to start without having to learn the
internals of both pyglet and cocos?

2. If I want an alpha channel for a snowflake sprite with soft edges,
what is the best way to accomplish that in cocos?

2a. Going back to the fire example, there seem to be two images
FIRE.JPG and FIRE.PNG - the former has no alpha channel, the latter
has a transparency channel. It looks like the demo is using the JPG
and thus handling alpha manually.  Is that true? Is it necessary or
can I use PNG with transparency/translucency? or TGA with an alpha
channel?

Thanks!
