Spacebrew is an open, dynamically re-routable software toolkit for choreographing interactive spaces. Or, in other words, a simple way to connect interactive things to one another. Every element you hook up to the system is identified as either a subscriber (reading data in) or a publisher (pushing data out). Data is in one of three standardized formats: a boolean (true/false), a number range (0-1023) or a string (text); it can also be sent as a custom format you specify. Once these elements are set up, you can use a web based visual switchboard to connect or disconnect publishers and subscribers to each other.
