Doomsday Computer

The Harrison is a multidimensional transportation device that is capable of transporting molecular-level matter to and from a select set of universes. This machine works by bending the rules of quantum physics, which, among his entire species, only Harrison has been able to do. The machine is set to activate July 3, 2023. Upon activation, the machine will cause a heightened level of instability in between the fabric of the universe, which may result in universal destruction. Gavin is the only person to have seen the machine, such as in "Harrison Doom Day", but has not said anything about it.

The machine utilizes the Pythagorean theorem in order to correctly solve equations involving triangles in relation to geological universe coordinates. In "Brick", Gavin upgraded the machine from Windows 95 to Arch Linux, and in the next from Arch Linux to macOS Catalina.
