	function bezier(pts) {
	return function (t) {
	for (var a = pts; a.length > 1; a = b) // do..while loop in disguise
	for (var i = 0, b = [], j; i < a.length - 1; i++) // cycle over control points
	for (b[i] = [], j = 0; j < a[i].length; j++) // cycle over dimensions
	b[i][j] = a[i][j] * (1 - t) + a[i+1][j] * t; // interpolation
	return a[0];
