from Mac Forums

As mentioned in millions of blogs out there, the Hologram iChat plugin didnt make it to the final build.. Thats a shame..
OSX Hologram
So some enterprising people over at Mac Forums have found a way to get it back!

Want the original .qtz file that didnt make it to Leopard? Straight from an older developer build, you can find it here Installation: Just place the file in your /Library/Compositions folder & enjoy.


Download

Update: Get this effect in Photobooth!
1. Extract HoloGit.qtz from the zip file.
2. Place it on your desktop for easy access.
3. Go to photobooth in your applications folder and right click to *Show package contents*
4. Navigate to content>resources
5. Drag the Hologram.qtz file from the desktop to this folder.
6. Locate the file *EffectsOrdering.plist* in this folder
7. Open the file with textedit
8. You should see a number of effects listed in that file. You should see user backdrop 1, user backdrop 2, and so forth in the last paragraph.
9. Replace the words *user backdrop 1* to *Hologram*
It should look like this: /Hologram
10. Save the file. Close all folders.
11. Open up photobooth and enjoy your newfound effect.
