rdc = master chladni.
Its really quite fascinating to see all these variations. Please keep going, I for one would like to see how far you can go with just chladni. It would be great to do an all chladni into.
What do we have so far:
chladni patterns in 2d
chaldni patterns in 3d as dots
chladni bump mapping
chladni 3d shaders
chladni image mapping (how esle to call it)
and rbraz suggested chladni plasmas
What else can you possibly come up with?
Next compo should be chladni compo - intro that uses chaldni in weird and wonderful ways. Would be cool.
