Rain script

Works well, a good price and easy to use.

This is what it says, with no rip-offs. A script you can copy and edit, with extensive documentation built in. Unfortunately, the way SL handles particle effects is a bit weird and I had trouble figuring out how to get exactly what I want. That is definitely not the seller's fault, but keep in mind that even with extensive documentation, if you want to customize your results, it's pretty technical.
