PLEASE HELP!

I'm created a frozen particle cloud and with the help of this little
script I manage to write by reading old discussion group e-mails, I'm
able to assign a random global rotation on the z axis for every
particle. Here's my question: Any tips on how to modify this script in
order to relatively and locally control the rotation of every single
particle.

dim v1

set cloud = ActiveSceneRoot.Children( "cloud1" )

Set particles = cloud.Particles

set v1 = XSIMath.CreateVector3

for i = 0 to particles.count - 1

randomize

v1.x = 0

v1.y = 0

v1.z = rnd * 120 - 60

set myParticle = particles(i)

myParticle.Rotation = v1

logmessage "Particle "&i&" Rotation.z: " &
myParticle.Rotation.z

next
