Impossible figure
Impossible figures are graphically two-dimensional, supposedly three-dimensional constructs in art that cannot physically exist. The figures are either paradoxes or optical illusions . They were first developed by Oscar Reutersvärd ; the Dutch graphic artist MC Escher created numerous such impossible figures in the 20th century.
The solution to the contradiction results from the two-dimensional representation in two dimensions and the sensory perception as a three-dimensional structure.
