[ros-users] SpawningObjectInSimulation

When I step through the Gazebo tutorial and I get to section 2.2 of
http://www.ros.org/wiki/simulator_gazebo/Tutorials/SpawningObjectInSimulation,
I don't see a box in my gazebo display. Does this work for other
folks? (In which case I'll go figure out what's wrong with my setup.)
