this is a quick hack, so i doubt the example below is elegant.
could probably be streamlined, but maybe it gets you in the right  
direction.
volker.

careful, email coding!

/* --- start listInterpol.js ---- */
var a = 0;
var b = 0;
var a0 = 0;
var b0 = 0;

function list() {
	var incrA, incrB, x, y, dist = 0;
	a0 = a;	b0 = b;	
	a = arguments[0];	
	b = arguments[1];		
	// calc difference	
	x = a - a0;	
	y = b - b0;	
	// max. distance	
	dist = Math.max(Math.abs(x),Math.abs(y));		
	if(dist != 0) {
		incrA = x / dist;		
		incrB = y / dist;	
	}
	for(i=0; i<dist; i++) {
		a0 += incrA;
		b0 += incrB;
		outlet(0, Math.floor(a0+0.5), Math.floor(b0+0.5));
	}
}

function set(c, d) {
	a = c;
	b = d;
}
