Very nice! I made a version of this effect for a little NYE thing years ago [0] (source here [1]). I first saw this effect in Iguana's Blastersound BBS intro [2]. I always thought that intro looked slick!

I always loved that intro too [0] :-) I implemented the effect in Pascal back then.

FYI, you can download the source code [1].
