Halloween house projection:
For our halloween decorations in 2016, I decided to do a "House Projection". The projection consists of a video playing on the front of the house showing ghosts flying through the windows, zombies crawling up the walls, etc. To make it as inexpensive as possible, I used a raspberry pi to play the video, a cheap bluetooth speaker and an old BenQ projector we had lying around the house. The video was made in iMovie.
