This plugin simulates an ideal resonator like a perfect guitar string. Such a string has certain modes or frequencies that it can vibrate on. This concept can be generalized to higher dimensions. In the world we live in, the story ends with three dimensions but mathematics gives us formulas to compute resonances of bodies in arbitrary dimensions. Software can easily execute these algorithms in the bounds of processing power which is only limited by your computers resources.
In particular, this plugin models the regular polytopes with perpendicular line segments, known as hypercubes. The plugin borrows its name from the four-dimensional hypercube, the tesseract.
