Pond ripple effect
Thanks avr-mike   Claswson's formula calculates a z-height in 3D space. This "height" (Which I'll probably scale 0 to 1) will be the amount of offset to apply to each...

Also, keeping in mid that each 'ring' is always the same colour all the way round, I don't need X and Y in the equation, just one of them. That should simplify things. Basically...

Pond ripple effect
  Thanks @clawson  This looks promising: so thanks for the link. z=(cos( 0.5sqrt(x^2+y^2)-6n)/(0.5(x^2+y^2)+1+2n), n={0...10}   I might experiment with that, and...

I like the interesting problems like this one. It made me think a bit harder and also it proved how useful the assembly listing can be too. As that Australian (not Austrian) guy...
