Impossible figures on CDs

Time Requiem

 Three basic impossible figures Penrose triangle, Devil's fork and crazy crate are depicted on the cover 2006 release of Swedish neoclassical progmetal group Time Requiem named "Optical illusion". There's also Escher's knot to the right of the cover, which don't belong to the class impossible objects but rather to Möbius stripes.
