Keywords: Machsches Ei, Objektdeformation, Perspektivetransformation, psychologische Optik, Mach's egg, object deformation, perspective transformation
A homogenously coloured egg in quick rotation may induce the impression of a "big swinging drop", of an elastic "body alternately elongating or shortening without rotating". (Metzger 1975). This example of reinterpreting perspective transformation as object deformation was given by Mach in 1886 and is demonstrated by a supplementary shadow demonstration of the phenomenon.
