Nice idea, I missed a few thing.

- on tab pressing, there's a percussive sound https://www.soundsnap.com/typewriter_electra_xt_old_electron...

- same happens on shift https://www.soundsnap.com/typewriter_erika_model_shift_press...

- same on other keys, like backspace

- once you reach the end of the page on some models, the carriage does't progress so you hit the same position over and over until you CR.

This is so cool to do. No error. No accuracy. No speed.
