StreetSign is a digital signage system, originally written for the TeenStreet 2013 (Germany) youth congress. It works with a single server, and multiple client computers connect over the network. It is lightweight enough that a Raspberry PI can run as the server for smaller installations.
Pkviz is a tool for plotting and cycling through and animating a series of network packets captured by tcpdump. What makes it unique is that the packets’ structure is visualized, not any labels and not time itself. Pkviz takes each byte in a packet and plots it out end-to-end, left-to-right, from the first byte to the last. How high the dot gets plotted depends on the value of the byte: bytes with a value of 0 are at the bottom and those which are 255 (0xff) – the maximum value of a byte – get plotted at the top. This might not be interesting for one packet, but that changes when you start looking at thousands of packets. Pkviz can cycle through thousands of packets in the set so you can see what happened on the wire.
Lifebox is a fast, lightweight, social photo and video gallery application that is designed to organize large amounts of media. It is able to differentiate between original and modified photos so you can upload your entire library to your server and highlight your favorite photos and videos into albums to share with friends. Lifebox also makes a distinction between albums and rolls, so a single photo or video can be part of multiple albums but only one roll. It extracts data from EXIF tags and XMP sidecars, making it compatible with the data from programs like Adobe Lightroom, Picassa, and iPhoto. Lifebox is social in that people and objects can be tagged, and they will receive an email when this happens. It supports authentication, so you can control who has access to what photo.
PyMei is a Python media center application. It's designed to run as a full screen application on an HTPC, navigated by a keyboard or an LIRC input device. It plays videos or shows other types of media using external programs like mplayer. With its plugin support and themeability, it's aiming to be a very extensible and customizable media interface.
