My son has this little toy that has two LEDs in it, one greenish-yellow and one Red. It blinks in this sequence that is one led on, off, on, off, on, off and then blinks the other in the same pattern and repeats. I took a slow-motion video of it here (1/8 speed).

What sorts of schematic that runs on a coin battery (with minimal components) could do this?
