    3d peer to peer chatroom where associated pairs of text gravitate

    A 3d chatroom where the things people write gravitate toward eachother based on total strength of associations between those short texts. Strength is a competition of who spends the most computing time trying to associate the texts, similar to Bitcoin's "proof of work" system. While there is unlimited space in the system overall, the space around any specific text is limited by 3d space, which drives competition for what people want that text to be associated with. It can be used like a forum or chatroom to associate text with responses, or to associate election candidates names with their positions on the issues, or to associate your website URL with things. Many possible uses, and a global competition for what gets associated to what else. In this peer to peer network, pairs of short text are communicated based on highest "proof of work" (see Bitcoin's design doc) on each pair, so the pairs of text that the most time is spent toward associating will spread through the network.

    InstaChat

    Hacker-like Retro Chat.

    Remember those Hacker movies chat applications? Yes, those with the green chars that appeared one by one on the screen, in real time, as the remote user typed them. That's what InstaChat aims for, a retro, multiplatform*, ncurses based real time chat, in which each key you press is directly sent through the network to the peer you are talking to. Checkout the Blog(Developers News) for NEWS! *Only tested on windows, but the only used libraries are ncurses and boost for socket and thread support so it should compile fine wherever these libraries run.
