Lucy Sun share her Random Distribution script for Maya, RandomDuplicator, which will allow you to duplicate one or many objects across a polygon objects surface allowing you to adjust random scale and rotation values.

This script is going to help users duplicate one or multiple objects to target object’s surface (polygon object limited)

Simply select an object or multiple objects, then select the target either in Object Mode, or alternatively, objects components such as verts wher eyou would like the objects to be duplicated – all fairly simple and straight forward, and if you want to check out the RandomDuplicator Script for Maya, check the page here.
