Play pong with your face! Watch my two roommates play a few rounds below:

This is based heavily off of Paruby's Snake-Face
Like it, I use MediaPipe Facemesh to estimate the positions of faces in real time. Unlike Snake-Face, I don't really care about the facing of each face (though maybe I could use it for some pseudo-3D-pong? Ideas for later!). Face-Mesh can be a little shaky at times (or I'm not using it right?) so try and have a very generic facial expression the entire time for best results. Motion blur might also interfere with FaceMesh.
Also in the time since I wrote this, FaceMesh looks to be deprecated. Whoops!
