Sculpt System

Hi guys,
I need to build a simple yet able sculpt application…
User gets a cube (for example) and can sculpt it to anything he wishes with few basic 3d tools…
Does anyone know any asset or anything that can help me with this?
I am not sure Unity3D is the right way to go but if anyone heard of anything familiar that can assist I will really appreciate the help.

Thanks
Alex

Here is something that can help you get started.

Not sure what you are looking for exactly, but this: http://www.pixologic.com/sculptris/ is a free sculpting app. It isn’t a plugin for unity, but you can sculpt to your hearts content…

I think he wants to sculpt “in-game”. Something to look at is some kind of voxel system, did a similar thing in another engine before were the player could “cut” stone statues in game from a big voxel cube.
