This is a light I made for a friend, intended to mimic the flicker of a fireplace. This schematic represents the design as I made it - it wasn't until later that I realized I could have just as easily replaced the ULN2803 with a single TIP120, ah well. I haven't breadboarded the circuit with a single TIP120. I used an attiny45 instead of the attiny13.

This runs the code from here:

I'm of two minds regarding just how realistic it is. It could benefit from tweaking. The LEDs on the one I built are half and half red and yellow, this gives the effect of an orange colour.
