+Self is a fast prototype based OO language which runs in its own JIT vm. Most development is done through interacting with live objects through a visual development environment called *morphic* with integrated browsers and debugger.
 
 Everything in Self is an object. All computation is done by sending messages to objects. Objects in Self can be understood as sets of key-value slots.
