I’m working on a light painting photo booth for my sister’s wedding & maker faire milwaukee: https://milwaukee.makerfaire.com/maker/entry/81/

It uses a webcam with max/msp software I wrote that sums exposures, making the light painting viewable in realtime.  A radio frequency remote triggers image capture and reset.  For the final installation, a flash will also be available to illuminate people in their painting.
