Thanks again mind-raper!

..and to post another variant for randomly-created particle attributes per a request in the MATRIX BULLET TRAIL thread
on how to get emitted particle instances (or even just particles)
to emit at random scale values:

Try this in a creation expression:

NOTE: you MUST add a radiusPP attribute to your particleShape, and apply this expression to that for this to work as you intend

The BOLD one is the one to use first, as it is what you asked for.
The rest are variants to try for fun

particleShape1.radiusPP = rand(.5,1)

OR

particleShape1.radiusPP = sin(time)

OR

particleShape1.radiusPP = sin(age)
