Dear Omz,

While I found your solution for Multiscene very elegant, I discovered that it does not work when calling variable such as size, bounds or dt.
The reason is that these variables are apparently generate during run.

A solution is to use the following definition

def setup(self):
    #print 'bounds', self.bounds
    #print self.size
    self.active_scene.size = self.size
    self.active_scene.bounds = self.bounds
    self.active_scene.dt = self.dt
    self.active_scene.setup()
def switch_scene(self, new_scene):
    self.active_scene = new_scene
    self.active_scene.size = self.size
    self.active_scene.bounds = self.bounds
    self.active_scene.dt = self.dt
    new_scene.setup()

with this modification the Multiscene works properly even with the nice example of multilayers with the snake.

Many thanks for all the work

@omz First of all, many thanks for all the good and useful work you have done. As I have an app with Bluetooth LE, I'll be happy to test the newest beta release.
