Attached is a 2d version of splode, which I think looks pretty good.
Major differences include:

- Use the default pyglet 2D projection
- Made all particles larger, spark sizes are now from a fixed set to
avoid distortion
- Increased velocity deviations quite a bit
- Added a growth controller to the fire to compensate for lack of perspective
- Made the fire particles rotate a bit faster

I CC'd the mailing list for posterity in case anyone one else is
interested. I'll probably add this to the "official" examples as well.
