Procedural Cloud System_cloud Painter

For the past few week i was playing with Houdini volumes. i had a look at Cmivfx Houdini fractals dvd  which gave me a lot insight into Houdini volumes(especially Clouds).So i thought of building procedural system for clouds in Houdini. i decided to have two separate tools in my system

      1)Cloud painter

      2)Grid Based Cloud System

Cloud painter is a simple tool with which useer can paint clouds on a grid and generate clouds out of the painted spheres.for now i m posting the screen capture of the cloud painter tool....soon will be posting Grid based cloud system.
