OE-Cake, OE-CAKE! or OE Cake is a 2D fluid physics sandbox application used to demonstrate the multi-physics simulation of the Octave Engine created by Prometech Software Inc. It was one of the first engines with the ability to realistically process water and other materials in real-time. In the program, which acts as a

, and support for gases, rigid objects, elastic reactions, friction, weight, pressure, textured particles, copy-and-paste, transparency, foreground and background images, and easy file sharing. OE-Cake was a casual/freeware version of the no-longer available PhysiCafe program marketed towards professional use, which was a Japanese language application utilizing the same engine. The name OE-Cake comes from the name of the engine and the word "cake" loosely means "draw" in Japanese; its name therefore means "OctaveEngine Draw". The developers of OE-Cake left Prometech Software Inc., and went on to form their own company, Phyzios Inc. They developed a web-app, Phyzios Studio, which lasted for a short time before being discontinued.

OE-Cake supports changing of the Parameters that define the physics and other behaviours in the game. To change these parameters, open an OE-Cake save with a text editor, scroll to the bottom, and change the values of a variable to change the behaviour of the game.
