I can color the layer, and make it move with this:

# layertest.py
from pygsear.Drawable import Layer, Circle
from pygsear.Game import Game
from pygsear.locals import BLUE, RED

class L2(Layer):
   def move(self):
       Layer.move(self)
       x, y = self.getPosition()
       #print x
       if 50 > x > 45:
           #print 'change'
           self.setBackground(color=RED)

layer = L2()
layer.center()
layer.setBackground(color=BLUE)
layer.path.set_velocity(vx=10, vy=10)

circle = Circle(layer)
circle.center(y=20)
circle.path.set_velocity(vx=5)

game = Game()
game.sprites.add(layer)
game.sprites.add(circle)
game.mainloop()
#


but it looks like Paths do not really understand layers...

I am looking at it now, but layers are still kind of experimental. Looks 
like
it would be good to have some way to say which objects are in front of
or behind others too....
