The harp
Every link in the footer is a string. Move the pointer across them and they vibrate. Turn the sound on, and they play a pentatonic scale that always sounds good.
- A real waveEach string is 96 points, and the vibration is computed with the wave equation, so it travels out from where you hit.
- As hard as you strikeThe faster the pointer crosses the string, the bigger the swing and the louder the note. Hold the mouse button to pull a string.
- Sound, when you ask for itSound is off until you turn it on, and the notes are chosen so any order sounds like music.
