I would suppose one of the very simple ways (?????) to do this sort of 
thing would be to have
one's puzzle pieces saved as either PNG or GIF images with rather large 
transparent borders.

Each of your puzzle pieces could overlay an animated GIF which would 
consist of all the frames to
produce the "airy-fairies": the two images would then be grouped.

So it would be the group [consisting of the puzzle piece and an 
underlying companion GIF] that
would be dropped on the target.

The group would contain code so that when it was dropped on the target 
the animated GIF would play
once or twice and then stop.

-------------------------------------------

Two problems here:

1. Controlling when the animated GIF plays [the first and last frame 
would have to be completely
transparent]: But, as far as I recall, this has been documented either 
on the Use-List or in the Forums.

2. Making the animated GIF images to "do" the sparkles.

--------------------------------------------

If I can get my mitts on a sparkly animated GIF [not much enthusiasm 
about trying to make one]
I will give this a go, as it sound both fun and potentially useful in my 
own Elementary school endeavours.
