The opening title sequence makes heavy use of LegoBoard. LegoBoard uses a library of thousands of photos of 1x1 Lego tiles on a black background and assembles them into a photomontage to make a single picture of a black background with lots of 1x1 tiles on it.
At first we used a program called ttfbanner (makes ascii art
words using ttf font files) to turn a Matrix-style font into ascii that could be used by awk
to create a tgl script to generate the falling letters.
