Ok, on the level of rubber mat (bent space). Roll a shot in a well with some side (non-radial)velocity (you may call it non-zero angular momentum), and watch a shot to move over elliptical orbit in the well of pure bent space. Roll it at higher side velocity - and instead of ellipse you'll easily get hyperbola or (if you lucky) a parabolic trajectory.
