555 timer running lowly - 4017 decade counter to give you individual outputs for every 555 pulse LED in a box with the letter on the front to light up connected to the 4017 output
Data sheets should tell tyou everything you need to know 4017 is a very common IC.

The easy, but more expensive, way is to use a microcontroller, like an Arduino. Then you can simply program the pattern in.
