I can send you a particle system I built and have been using recently but if you don't have After Effects and trapcode it isn't much use. It's similar to what they build here.

It's about an hour of work to follow the tutorial and build it, then another hour to track and comp usually. But if you don't have particular it will end up being more expensive than a practical option, I'd wager. We just did a similar project and found post was easier especially for wide shots.
I appreciate the offer, but yeah -- no After Effects or anything similar, and no time once the footage is shot to get up to speed and get it done anyway. I would need to shoot it both ways anyway -- with and without the practical effect -- just in case. So may as well concentrate on perfecting the practical effect. I've got all spring, summer and fall to work on that.
Really, though -- thanks!
