Small, fast in-kernel windowing system

FBUI is a small, fast in-kernel GUI windowing system for the Linux kernel whose core is currently about 32kB large. It lets you put windows in each framebuffer-based virtual console, read keyboard input, track a mouse pointer, and respond to typical GUI events. Each process may have more than one window, and accesses its windows completely independently of all other processes. It supports windows on every virtual console, and there is no concept of parent and child windows. Each virtual console can have its own optional window manager process
