The main part of the demo has been partially converted from the C64 demo The Cat, released by Euratom and Quality in 1989. Both versions feature the same SID tune The Cat composed by Hayes aka Markus Mueller.
The famous rotating animation of the framed cat originally comes from the "El Gato" animation demo created by Kevin Sullivan and released under the sign "Blair-Sullivan Computer Graphics & Animation" (Menlo Park, CA, USA) with code by Aegis. This animation is Kevin Sullivan's entry to the Badge Killer Demo Contest. An excellent digitised cat in a frame runs along as the frame rotates around 360°. Actually one meg on Amiga computers is required for a full spin but the effect is still good in half meg. The animation animation has mainly been spread through Pack disk 1987 collection by Alpha Flight 1970.
