Xoo is a graphical wrapper around xnest
Xoo is a graphical wrapper around Xnest/Xephyr, the nested X server. You can make Xnest look like a particular device's display and set up buttons on that device. This is useful for embedded developers who want to simulate a target device on their desktop machine.
