AS tute - random movie placement

I have a clip in the library with the linkage ShootingStar, and I need this to be randomly placed all over the stage at intervals of between 0.1 and 1 second, as well as random sizes between 100% and 300%.

Oh, and having a random tint to it.

I canno’t for the life of me find a tutorial, though I imagine something generating water drops would be along similar lines.

Thanks@
