Micro Snake is based on a simple snake game by Simon Huggins. This version of the snake (worm) game is very small and only utilizes ANSI escape sequences to draw the board. Hence it is very suitable for small embedded systems with only serial or SSH console access. The code uses no curses or other heavy libraries, only ANSI escape sequences and the Unix "stty" command to setup and restore the display.
encapsulate provides its client process the same environment it's started in, except for some limitations: encapsulate remounts the whole filesystem read-only, except for user-selectable regions which are mounted read-write. It also isolates the process from the system's process table, network interface, IPC, and shared memory tables.
getxbook is a collection of tools to download books from websites. There are tools to download from Google Books' "book preview", Amazon's "look inside the book", and Barnes and Noble's "book viewer". There is an optional GUI written in Tcl/Tk, and some shell scripts using OCR to create plain text or searchable PDFs and DjVu files from the downloaded books.
