I can stare at it for a loooong time:ko:, try changing some of the settings…fun

```auto

w = 600
h = 400
sat = 127
this.onEnterframe=function(){
	clear()
	r_R_A -= .152
	r_R_B -= .175
	g_R_A -= .01
	g_R_B -= .054
	b_R_A -= .045
	b_R_B -= .178
	rA = Math.sin(r_R_A)*sat+128
	gA = Math.sin(g_R_A)*sat+128
	bA = Math.sin(b_R_A)*sat+128
	r_B = Math.sin(r_R_B)*sat+128
	gB = Math.sin(g_R_B)*sat+128
	bB = Math.sin(b_R_B)*sat+128
	col = bA << 16 | rA << 8 | rB
	beginFill(col,100)
	lineTo(w,0)
	lineTo(w,h)
	lineTo(0,h)
	lineTo(0,0)
}

```
