I have added a "custom_particle" feature to the particle_system patch,
when it is used, the script within the custom_particle {} block is
executed for each particle(similar to the motion_blur patch, which I
based some of the code on), and the objects placed in a union. The
particles are automatically translated to position and scaled to size,
and an optional random rotation is available.

It does sort of resemble a bunch of multicolored candy... :-)

Cool :) This should make for some cool powdery snow falling off a roof or
something.
All your test images seem to have just a few particles per fountain, is
it slow? Or are you just using small numbers for the test renders?

Hmm, that is an interesting idea...

No, it is actually quite fast, a couple seconds parse time and less than
5 minutes to render with water texture. One part of the reason is that I
have only implemented point emitters, so many of the particles are
behind others or packed into a small region of space. I am working on
new emitter types now...
Also, I purposely lowered the number of particles in this scene so you
could see the individual particles, to show off the custom_particle
feature.
