Here is an RGB ible made from a 5x7 LED brick of 105 LEDs
That is 35 Red, 35 Green and 35 Blue LEDs.
And a simple circuit using a programmable Parallax Stamp
micro-processor to display any color at any dot.

One of my early ibles using a wire wrap circuit design...  .  A

Do you want to make a programmable LED display like this?

Or do you want to wire up some LEDs onto a perf board so they spell out something?

If you want the later then you will need to use an LED calc. This will allow you to take the input voltage, number of LEDs and the power needed by the LEDs to figure out the basic wire diagram you'll need to connect them to the power source. Once you know that its just a matter of laying out th LEDs in the pattern you want. Then you've made your own LED sign.

This is an LED Matrix that is made for the Arduino. Don't know what Micro Controller you plan to use but you can find LED matrices all over the place that can easily be connected to a Micro Controller and programmed.

You can also create your own matrix.
