Abhishek Singh has created this awesome GIF camera from two Raspberry Pis. Called the Instagif NextStep, a Pi 3 with a camera and preview screen records a short video clip and then transmits that clip to a Pi Zero which is then ejected in the form of a cartridge. The cartridge has its own Pi, battery and screen and displays the GIF recording.
All the parts are held together using 3D printed cases. You can see a video of it in action below and read a lot more about the build here.
