Here, in a reference photo I stumbled across, is probably the best caricature of Nick Cave, and it just happens to be an accident:
The accidental caricature was caused by angle of the sun to the wall, and the angle of the wall to the camera, combined with how the slats in the siding break up the image.
I isolated and highlighted the area of the photograph.
This may have been truly an accident; quite likely the photographer saw the shadow and seized the opportunity. Either way, it's brilliant.
...and the funniest part... I think it looks like Funky Winkerbean. LOL
