At first glance this just appears to be a gimmick, but the more you play with it, the more you find uses for it!
TOTD first saw it used by the keynote speaker of a two-day conference. He’d taken the pre-published conference proceedings and run them through it to produce a single page image representing the conference. He did the same with all the notes he’d taken across two days. It worked well (and the two together were interesting to compare).
You can use it in a presentation as a title (or end) slide. You could use it as the cover of a dissertation (after putting the text through it).
While it is still a gimmick in many respects, it’s a useful way of representing a lot of text in a simple, easy to understand way. If nothing else, for those who like words, it can produce interesting art.
