For 2nd image, we have a directional light at the y-axis. 
We only have two point colors: that is blue and yellow to 
give the effect on the globe and orange. The wall, which is 
slightly reflective and is checkerboard design. The table is a 
design take contains the US$1 bill. In front of the wall, there are 
three spheres: a metal ball, a toy globe and an orange. Light 
falling on the toy globe, orange or the table will be reflected 
onto the metal ball. On the metal ball, there's also a spot light 
(red color) that we implemented that shine directly on the metal 
ball and does not spread out like the point source. 
We also use anti-aliasing to smoothen the edges.
