Today’s invention is inspired by this digital artist.
If there is a statue in your town depicting someone who is now deemed politically incorrect, simply
a) perform a laser scan of the statue
b) use that to design a thin shell which might be clipped together over the offending statue.
This shell, which could be pre-weathered to have a patina of age, could portray someone who is a more modern hero, until they too become unacceptable, for some reason.
