Flickr member xmasons shares this easy recipe LED blinkage using a 4060 binary counter chip.
The circuit’s low price and part count make it a good choice for adding some pizazz to models and props. Check out Starship Modeler’s tutorial and try experimenting with different configurations.

I’m not sure it gets any more simple than just using a blinking LED. Granted, you don’t get much control that way.
I always like the LM3909, too bad it’s discontinued.
One D cell would power a led for over two years
However, if you need a complex method, here is a tutorial which shows blinking LED using an AVR microcontroller.
