These Pure Data/Gem patches make use of a (web)cam. Please make sure to connect one prior to launching Pure Data.
Since only one patch can access the video camera at a time, please close the first patch before opening the next one.
On Linux and Windows doubleclicking on a file may cause another instance of Pd to launch. Please use the open dialog from the File menu instead of clicking on the files.
