Starbox — a music box with real stars in it.
Starbox is little app I originaly made to lull kids while parents can learn about stars and constellations. Actually, the exact opposite is happening and parents get asleep in no time. Works even better with a beamer.
It allows to load any MIDI soundfile, so you can at last choose your favourite disco-funk, symphonic or heavy-metal track as a lullaby. Beware that it will be rendered through this gentle music-box-like sound synthesis though.
