There are some prety cool controls here, if you know how to look for them. For
instance, if you want to change the brightness of the light, you can type in a new
number in place of 1.000000 . Or, if you hold the mouse between the two black
arrows on the right, you'll see it change to a double-arrow icon. Click-and-drag up
and down and you'll change the brightness dynamically.
Next, to the LightColor field, you can click the magnifying glass to bring up a color
palete display. You can also click on the mouse pointer icon to get a color picker,
click in the scene to sample the surface's color. Try both of those now.
