If this is cast in copper, which it looks like (and his more recent work would support this theory too) then I like the geographical relevance. The contry’s rich mineral deposits are what has provided the wealth in the past.
This reminds me of the terrifying fortune machine in the movie Big with Tom Hanks, where his wish gets granted and turns out to be a curse.
There is not much description on the site, but I’d like to think this one moved too.
Also nice that if this is cast copper, then the casting is now worth much more than the trillions of Zim dollar banknotes it looms over.
