hoser acts as an "object hose" - it 'sprays' out copies of an initial object as you move the mouse, as with a 2D paint program. It can be used for special effects, paint spills, etc. You could use hoser to scatter rocks, blades of grass, anything where 'spraying' objects would save time over repetitive copy,move actions.
The module really comes into its own when used with metaballs: puddles, blood splashes, melting candle wax, snot.. all kinds of disgusting bodily emissions!
hoser is fully supported under version 3.1 and higher of trueSpace.
