Mac OS 7.5 Easter Egg - Resedit Pig Mode

1. Run ResEdit and close the splash screen and/or Open dialog
2. Hold Option + Shift + Command while choosing About ResEdit… from the Apple menu.
3. A dialog comes up asking if you want to turn pig mode on. Click OK.
4. If ResEdit was run on an old mac like an SE from a floppy, the drive will 'oink' a few times each second.
5. To turn pig mode off, repeat steps 2 and 3.
