this project works with your camera to sense your face and puts a mask on it. because it uses your camera it requires your camera to be enabled. you can quickly press ←↑→ in that order to stamp the mask in a place. you can also press ↓ to draw, to stop you press ↑. you can press the space bar to clear the screen from everything that you drew or stamped.
I used the camera extension and the face sensing extension. the camera extension was used to "turn off" your camera when your face isn't there, the face sensing extension was used to put the mask on your face. I used the Makey Makey extension to do inputs, and pen extension for drawing.
