US $1 note
275 X 340mm 2002
$1 cut into concentric circles about 1mm wide and arranged between seven
layers of glass to create an effect like pond ripples.
The glass isn't perfectly clear (it has a
slight green tint) - so the deeper layers are slightly darker and
greener which also adds to the sense of depth.
I assume this artwork would be illegal in
the US (destroying currency). I'm not in the US.
