wiipdf is a tiny tool to present a PDF using xpdf and your Wiimote. You start it by providing it the bluetooth ID of your Wiimote (use hcitool scan to get it) and the path to the PDF you want to present. wiipdf then tries to connect to your Wiimote (press buttons 1 and 2 at the sime time on your Wiimote to enter discoverable mode). As soon as the connection is established (usually 3-4 seconds), wiipdf launches xpdf with the given filename. You can now press A or B on your Wiimote to go forward or backward one slide. Pressing the home button ends the presentation. Each keypress is confirmed by a short rumble.

x11vis is a visual and interactive tool for debugging X11 clients. Unlike other tools such as xtrace, it displays human readable IDs on all requests, no matter at which point in time the information becomes available. To help you cope with large amounts of data, it displays only the most important information by default, automatically folds sequences of boring requests, allows you to filter by packet type or client, and provides markers for navigation. Instead of assigning a number to each connection, it displays the command line with which that client was started.
