Hi Jaylfk:

I've worked before with some Processing users to provide iGlasses support for their projects, but it's tricky.  iGlasses keys off of the name of the running application, and when processing starts running a project that imports the video library, it starts a new process with a temporary name.
Also, when a user saves their project as a standalone java app, that app will have whatever name they give it.

It is possible to manually add the name of your exported Processing application to the list iGlasses uses when deciding what apps to load into.
To do this, it helps to have the OS X dev tools installed because it makes it easier to edit plist files, but it's not essential.

Here's how:
1) Go to your Applications folder and find iGlasses Manager.
2) Copy and paste a new copy of the iGlasses Manager to your Desktop.
3) Using the new copy of iGlasses Manager, open its bundle by Control-clicking and saying "Show Package Contents".
3) Open Contents/Resources, and find the apps.plist file.
4) If you don't have the dev tools, you open the plist file by dragging it onto TextEdit.
5) Add a new key/string pair for your app: for the key, use the name of your export processing app, and for the name, whatever you want.
For example:

<key>sketch_070609a</key>
<string>Sketch</string>

6) Then, save the file and open the iGlasses Manager (the copy).
7) Find the new app you added and check it off. (i think he meant to say ON)
8) Apply the changes.

That should be all you need to do.

Thanks,
Ken
