Salut à Toi (or SàT: "Hi to You") is an XMPP/Jabber client with multi-frontends. You can use it on a desktop (Wix), with a console interface (Primitivus), as a command-line tool (jp), or on the Web (Libervia). A plugin architecture is used to make it modular. With SàT, you can perform all the expected XMPP functions (instant messaging, multi-user chat, file transfert, etc.), but you can also use your email client (MUA) to read and send your XMPP messages, play games, do microblogging, pipe Unix command results, make scripts, etc.
Card Stories provides a server for a networked guessing game using picture cards. One player (the "author") starts the game by choosing a card, picking a word or a sentence to describe it, and sending out invitations to others to participate. Each of these players receives seven cards and has to pick one that best matches the author's description. Once enough players have chosen a card, the author displays all chosen cards and the players try to figure out which one is the author's. If at least one but not all of them guesses correctly, the author wins, along with the players who guessed correctly. Otherwise, the guessers all win.
