+(1) Grab the latest sprites.py from here [1] (I made some changes)
+
+(2) In game.py, you need event handlers  for draw:
+        self._canvas.connect('draw', self.__draw_cb)
+
+and the corresponding method:
+    def __draw_cb(self, canvas, cr):
+        self._sprites.redraw_sprites(cr=cr)
+
+(3) In game.py, you need an __expose_cb:
+
+    def __expose_cb(self, win, event):
+        ''' Callback to handle window expose events '''
+        self.do_expose_event(event)
+        return True
+
+    # Handle the expose-event by drawing
+    def do_expose_event(self, event):
+
+        # Create the cairo context
+        cr = self._canvas.window.cairo_create()
+
+        # Restrict Cairo to the exposed area; avoid extra work
+        cr.rectangle(event.area.x, event.area.y,
+                event.area.width, event.area.height)
+        cr.clip()
+
+        # Refresh sprite list
+        if cr is not None:
+            self._sprites.redraw_sprites(cr=cr)
+
+(4) Also, in game.py:
+        surface = cairo.ImageSurface(cairo.FORMAT_ARGB32,
+                                     self._svg_width, self._svg_height)
+        context = cairo.Context(surface)
+        Gdk.cairo_set_source_pixbuf(context, pixbuf, 0, 0)
+
+(5) Please add a summary field to activity.info:
+
+summary = prompts learner to tell a story by displaying images at random
+
+good luck.
