theRelativity is a funky little 3D application created by the developer of OLE Coordinate System, the engine which SCEJ's Echochrome was originally based on. Virtual characters are now placed inside cubes instead of above them, and selecting any of the four modes will affect the shape of the corridors from the autonomous character's view.
The original mode resembles Echochrome and OLE Coordinate System the most, while translation mode works by joining up two cubes at the exact moment a character moves from one cube to another. Deformation mode attempts to draw the connecting corridors in 3D global view to reflect the actual pathway taken by the virtual character, while impossible object mode will draw impossible shapes in the style of M. C. Escher's artworks to connect corridors, even when such a shape could not exist in natural form. You can quickly switch between modes by using the F1 to F4 function keys as well.
