This is an interactive version of the viral "leekspin" video in which a woman spins a leek while singing a song. The video only plays while you're turning the crank, and  the tempo and pitch of the song are controlled by your cranking speed. There's no scoring or penalties, but cranking at the right cadence to make the song play at a steady pitch and tempo is a good way for a new Playdate owner to practice crank control and also a good way to demo the crank for someone unfamiliar with the device.
