xremote is a simple tool that lets you grab the mouse and keyboard of another machine and control them with your local mouse and keyboard. It creates a form of remote control of other machines. All mouse- and keyboard-actions on the local machine are forwarded to the remote display.
vt52vnc is a VNC viewer which can be used on prehistoric green monochromatic terminals called vdt52s, which are capable of vector graphics. It is functional and nicely displays X on the terminal, but without the routines for dithering, compression, and password support. Its architecture provides a framework to add those features if needed.
Multixterm creates multiple xterms that can be driven together or separately. It can be used to login via SSH to multiple hosts and control them simultaneously, or for ad hoc things where you want to see the results as you type. Each xterm may also be driven separately. Multixterm is scriptable so that you can easily fire up, for example, a dozen xterms with a single command, tiled nicely on your screen. In addition to SSH, multixterm can drive rlogin, telnet, passwd, or any program that runs in an xterm.
DIET-PC (DIskless Embedded Technology Personal Computer) is a software kit enabling IT professionals to build embedded Linux appliances based on commodity PC or Mac hardware and various commercial embedded appliances. The focus is on platform portability, OS fundamentals and developer friendliness, rather than the end-user UI. The distribution is intended primarily for desktop graphical appliances, particularly thin clients (using the X11/XDMCP, ICA, RDP, and RFB graphics protocols). Although originally a network-booting OS, DIET-PC works well with various forms of solid-state persistent storage and hence is no longer strictly "diskless". The project uses QEMU virtual machines running Debian Linux (under Windows) as self-contained development environments, and hence may also be of interest for its unusual (non-x86) QEMU accomplishments.
Spinner is useful for keeping telnet and ssh links from dropping due to inactivity. Many firewalls and some ISPs drop connections when they are perceived as idle. By having spinner running, the server is constantly sent a tiny amount of data over the link, preserving the connection. Spinner thus acts as a keep-alive. It displays a little "spinning" ASCII character in the top left corner of your terminal. It supports any terminal capable of handling VT100-style escape codes. Spinner can also function transparently by only sending null characters to the terminal. In this mode Spinner supports any terminal. It also has a mode called "Ghost in the Machine" in which you can use Spinner to write the spinner character to any TTY, not just your own.
