Escher-montage
Josh Sommers
Josh Sommers, who created a wonderful set of computer rendered images with impossible figures, created photo montages with impossible figures. One of them is a copy of Escher's artwork "Drawing hands", in which he replaces pen in hands to pencils. The other is impossible hand-railing.
Sculpturing hands is a variation of
Escher's "Drawing hands"
with scupturing instruments.
There's also another variation of the artwork with replacing instruments
"Carving hands" by Phil Allin.
