Simple laser cut picture frame
A simple picture frame, which can be used with an small display (e.g. https://www.adafruit.com/products/947).
It's not very nice, but was used at a open cultural data hackathlon (http://make.opendata.ch/wiki/event:2015-02) and had to be a quick&dirty solution to hide the display, a camera and a raspberry pi.
Created from a picture and then vectorized with Inkscape.
