A remarkable John O’Brien cartoon in the 2/3/25 New Yorker, in which a cowboy whips his lariat in pursuit of a cow, with a stark desert landscape of mesas and buttes outlined behind them:
(#1) But wait! That line in the cartoon is both the lariat — the figure — and the outline of the landscape — the (back)ground — so that looking at the cartoon, you perceive the one, then the other, shifting from one to another: what is figure, what s ground?
It’s a percept-shifting visual illusion, exploiting an ambiguous image, in particular a figure-ground ambiguity. Here done as a joke in a cartoon, a visual parallel to what I’ve called sense-shifting pun jokes.
