So, I made a sign because of an AskReddit thread.
I resubmitted this link because my original album did not have any information on the process.
I used some perfboard, and about 90 super bright LEDs arranged in the letters to make this happen.
I put four LEDs in series with a 100 ohm resistor, and duplicated that 23 times.
The only challenging part was how to make chains of four as the letters did not use even multiples of four to make. It is pretty cobbled together, but it works and that is the important part.
The sign: this link has the instructions on how I did this piece of work.
Info: this LED array is around (26,000*90) = 2,340,000 mcd, that is milli-candela. It is brighter than hell. That is 2300 candles if they were all arranged to only point vertically.
