Agamotto is a great content type to show layers or a sequence of development. This post on X by Chase Lean @chaseleantj showing the development of the text-to-image AI tool Midjourney really suits the use of agamotto.
Regarding English language teaching, it can be used to elicit sequencing language to talk about how technology has developed such as “first, then, next, a few months later, currently” etc.
Or it could be used as an engaging starting point for discussing how other technology has developed rapidly.
