I'd like to build a system that can deliver a stream of droplets of water that I could turn on or off and control the speed using a computer. Ideally I'd also have control over both droplet size and the rate of droplet formation. The aim is to simulate rain.

Ideally, i'd like to have a matrix of droplet-generators so that I could create for example a 16x16 grid of droplet generators.

How much control would you like?, would a few preset sizes/rates that could be selected from work, or do you want continuous control? The former would be quite easy by using multiple valves connected to different types of nozzles/sprinklers. Since the parts for lawn sprinklers and appliances like washing machines are mass produced, low to moderate pressure plastic body solenoid valves are quite economical. Continuous control will probably be more expensive, proportional motorized valves are available, or, if the water is being recirculated, a variable speed pump could be used. Variable droplet size might be more difficult, it might require a custom made nozzle, one might have to do some experimentation.

There are companies that produce only spray nozzles for industrial uses.
I'm sure that if you do a little searching that you will be able to find a nozzle that will suit your purposes.
Many of these manufacturers have local distribution outlets.
As a starting place try; http://www.bete.com/

I built a spray unit for my home heating system to add and control the humidity in the air directly after leaving the furnace, and found some spray nozzles that produced a very small spray pattern and fine droplet size so that I don't get any moisture accumulation in the ducts. It took me a while to find the right kind of nozzle.

The key to this is height. Because of surface tension, if you start with something close, the drops will be the correct size once the reach terminal velocity. I needed to do this once and we used something that looked like one of these large round shower heads and set it up on the third floor of our labs atrium. It worked perfectly! Good luck.

Computer controlled Sprinkler on the roof maybe.

yes they do, it depends on the amount of cloud, wind etc.
