Apple iSight with a Raspberry Pi inside
PiSight
I put a Raspberry Pi inside an Apple iSight. You can read more about the PiSight on Medium.

Software
The PiSight camera implements the UVC standard via the Gadget API, which turns the Raspberry Pi and camera into a plug-and-play USB webcam. I used the instructions in David Hunt's blog post, with a few modifications in my own fork of uvc-gadget.
I consolidated these steps into a setup script, so you simply need to install Raspberry Pi OS, enable the camera and serial interfaces via raspi-config, and then run:
git clone https://github.com/maxbbraun/pisight
cd pisight
sudo ./setup.sh
Update: There is now an alternative setup option thanks to the showmewebcam project, which is better maintained and provides pre-built optimized images (provided you don't mind seeing Piwebcam instead of PiSight in settings).
