Yes. Individual lettering is not how you would do this. Unless you had a LOT of time to kill. I’m not an AfterEffects guy, but my guess is, they used a stroke recording function to trace or freehand draw a more conventional sketch of Biggie, then, using the recorded strokes as the guide, some plug-in automatically or semi-automatically replaces the weighted lines with text of apropriate size. I am certain there is more to it, but that’s my guess as tot he main technique.
If you have a copy of Synthetik StudioArtist, you can sort of fake this semi-automated with a brush set to paint with text instead of color.
