# Short description #
The mathematical fascination with *ink marbling* is that while rakings across
the tank stretch and deform the ink boundaries, they do not break or change
the topology of the surface. With mechanical guides, a raking can be undone
by reversing the motion of the rake to its original position.
Raking is thus a physical manifestation of a homeomorphism, a continuous
function between topological spaces (in this case between a topological space
and itself) that has a continuous inverse function.
The package comes with 15 predefined *basic actions* like:
- drop
- line-drops
- serpentine-drops
- coil-drops
- normal-drops
- uniform-drops
- concentric-rings
- rake
- stylus
- stir
- vortex
- jiggle
- wriggle
- shift
- turn
Also some *spray-actions* (post-marble actions) like:
- normal-spray
- uniform-spray
Also a *shadings* option to generate shading effects (post-marble actions)
With these commands one can create quite artistic marble-like patterns following
the rules of fluid mechanics.
