Sophy Wong and her husband have built themselves a selfie booth using a Raspberry Pi. The booth has a camera (obviously) and a screen which displays a facial expression. The selfies taken are printed out by a thermal printer and the bot also emits sounds appropriate to what it’s doing. A full build log, including lots of photographs and all the files you’ll need to laser cut and/or 3D print the case are available over at Adafruit.
