You've reached an interactive, collaborative and easy to use take on a Kanban card wall that was written for the RailsRumble 48 hour code competition.
Simply create cards in your backlog that express your units of work in a 1 or 2 sentences. As cards are progress through their lifecycle, they are dragged through swim lanes to represent their current state.
When a card is completed, a new one should be pulled out of the backlog and into the current sprint. You can move cards between sprints by putting them in the backlog.
