Particle systems: FIRE, SMOKE, RAIN

Hi! I want to share some particle systems:

Hi Sunbleached,

Your "Fire" and "Smoke" scripts use the same texture and similar start and end colors (grey). I imagine they'll both look like smoke. Wanna check that out?

They also use different invocation methods, Touch->Fire, Rez->Smoke, Message->Rain. That's not a problem, but might confuse newbies.

Scripting is fun, particularly with llParticleSystem(). My newest avatar is constructed using nothing but that call and one texture.

Hi! 

I specifically made different options so that people could use it differently in these examples.
Thank you, I hope you enjoyed it!

It’s interesting to see your avatar from the particles!

There are two particle effects that only fire for a second or two every 10-20 minutes, but this gives you some idea what I look like.
