Width Modulation that fades an LED?

I have a better idea. you use a 4017 counter like in the pic, but instead of lighting 10 LEDs, you just light one using 10 diff resistors. the first 5 resistors are in decreasing order to make the LED get brighter, and the last 5 increase the resistance to make it fade. you might leave the first and last outputs unconnected so it's completely off for 2 counts. the 555 determines the rate of the fade.
