I think the idea is basically that sets of 2 panel cartoon are reconfigured based on the phrase you enter? Or maybe it's entirely random? The basic style is indebted to the little proselytizing pamphlets of Jack Chick.
Actually, it's not just the style here that's been copped, but the images from Chick's tract, "Charlie and the Ants." This reminds me a bit of the Minneapolis-based The Fascist, a great zine from the 90s that featured Situationist-y cut & paste detournment of Archie comics. (In that case, the language used by Archie & pals was entirely Marxist. Heh, heh.) Anyway, I went to the site itself to see how this worked--but I can't see any relationship between the text I typed in ("What goes up must come down") and the resulting language ("It's log!" "Argh!") ... but, fun nonetheless ...
