Control Icon
 

How do I create a Control Icon for a joint? Any help would be greatly appreciated!

Control icon? as in a controller in your 3d Workspace or in the user interface?
Describe what you want.

Are you talkin about an IK handle or a null or similar, to control a rig.

If you download the Generi Rig, which can be found at:

http://andrewsilke.com/generi_rig/generi_rig.html

there are little symbols automaticly attached to the perspective camera. When you click on those symbols, they select the joint it symbolizes. What I am wondering is how do I create those for my own models?

on the same page that you posted for us, further down is this text:

-- The Trigger UI --
The trigger UI is a bunch of nurbs surfaces parented to the camera - these surfaces are the triggers for selecting the character controls. When you select a trigger the corresponding puppet control is selected on the character. You can move and scale the trigger icons by clicking the x's. The transparency of the icons can be set on the centre of gravity control (cog_ctrl). If you don't like them you can switch them off completely in the layer bar.

To switch the UI to a different perspective camera create a shortcut with the following command:

asSwitchUICam;

Make sure the correct scripts are installed for the Trigger Interface to work.

If you would like to create your own triggers you can do so with the trigger script. Use the following command as a shelf button, hotkey or type the command in the command line:

zooTriggered;

after that you're either on your own or i hand you over to the mel scripting gods on this site
