To use Show Look At, enable the Develop menu with , then Develop > Avatar > Show Look At. (On viewers before 2.0, try Advanced menu > Character > Show Look At.) The LookAt point is an animation hint, viewers use it to know what way to turn your eyes, head and torso.
Thanks to Richard Linden for this info on what the different colors mean:

If you focus on yourself, or use Alt+arrow keys to move the camera around, an arbitrary focus point several meters in front of you, not pointing at anything in particular, is used.

There are various values that control how long these lookats are valid, how they prioritize relative to each other, what the percentage chance of them triggering is, etc. You can find the settings in character/attentions.xml (for example, C:\Program Files\SecondLife\character\attentions.xml).
This video shows how Show Look At works in action:
== Tweaking attentions.xml ==
The standard attentions.xml file looks like this. There are separate sections for when you are wearing a male or female shape, but by default the numbers are set to be the same.
<?xml version="1.0" encoding="US-ASCII" standalone="yes"?>
<linden_attentions version="1.0">
 <gender name="Masculine">
 <param attention="idle" priority="1.0" timeout="3.0" />
 <param attention="auto_listen" priority="3.0" timeout="4.0" />
 <param attention="freelook" priority="2.0" timeout="2.0" />
 <param attention="respond" priority="3.0" timeout="4.0" />
 <param attention="hover" priority="4.0" timeout="1.0" />
 <param attention="conversation" priority="0.0" timeout="-1" />
 <param attention="select" priority="6.0" timeout="-1" />
 <param attention="focus" priority="6.0" timeout="-1" />
 <param attention="mouselook" priority="7.0" timeout="-1" />
 </gender>
 <gender name="Feminine">
 <param attention="idle" priority="1.0" timeout="3.0" />
 <param attention="auto_listen" priority="3.0" timeout="4.0" />
 <param attention="freelook" priority="2.0" timeout="2.0" />

</linden_attentions>
Why would we want to change this? One reason could be the "stop camming me!" phenomenon. Sometimes people can be upset by the hover, select and focus crosshairs appearing on their heads, so we can tell our avatars not to use those. Simply set their priorities to 0.0 like so:
<?xml version="1.0" encoding="US-ASCII" standalone="yes"?>
<linden_attentions version="1.0">
 <gender name="Masculine">
 <param attention="idle" priority="1.0" timeout="3.0" />
 <param attention="auto_listen" priority="3.0" timeout="4.0" />
 <param attention="freelook" priority="2.0" timeout="2.0" />
 <param attention="respond" priority="3.0" timeout="4.0" />
 <param attention="hover" priority="0.0" timeout="1.0" />
 <param attention="conversation" priority="0.0" timeout="-1" />
 <param attention="select" priority="0.0" timeout="-1" />
 <param attention="focus" priority="0.0" timeout="-1" />
 <param attention="mouselook" priority="7.0" timeout="-1" />
 </gender>
 <gender name="Feminine">
 <param attention="idle" priority="1.0" timeout="3.0" />
 <param attention="auto_listen" priority="3.0" timeout="4.0" />
 <param attention="freelook" priority="2.0" timeout="2.0" />
 <param attention="respond" priority="3.0" timeout="4.0" />
 <param attention="hover" priority="0.0" timeout="1.0" />
 <param attention="conversation" priority="0.0" timeout="-1" />
 <param attention="select" priority="0.0" timeout="-1" />
 <param attention="focus" priority="0.0" timeout="-1" />
 <param attention="mouselook" priority="7.0" timeout="-1" />
 </gender>
</linden_attentions>
You will need to restart the viewer to see the changes.
