Thanks for the kind words. The code is a bit unoptimized as I don't have much experience with using tline(). So I ended up with a code size over the maximum allowed. I had to reduce portal glitch code and take out sfx just to get to the size limits.
I decided the sequence had to be displayed on screen because in the movie the glyphs expressed coordinates. As a nice side effect, looking at the next glyph allows you to plan ahead, if you're fast enough.
