Raise two hands to the webcam. A line connects your two index fingertips, and its
length sets the pitch. Coloured notes fall toward the line; match your finger spread to
each note's width as it crosses — a meow plays at that pitch on every note. Pick a
level from the buttons up top: Twinkle, Memory, endless Random, or free-play Pinch.
Memory plays the full recording underneath and asks you to perform the lead vocal —
follow the falling notes to sing it back with your hands.
Pinch is free play with no falling notes: pinch both hands (thumb to index
fingertip) to sound a meow at whatever pitch your finger spread is at.
Edit the CONFIG block at the top of this file to write your own melodies, or drop a
real recording in as meow.wav.
