Bebot is a very cute synthesizer for the iPhone, that does not only sound quite nice, but also will melt the hearts of all robot-lovers out there. It features a "singing tin robot" as a character, that "sings" the stuff you play.

There are different parameters, like waveforms to select, effects like delay and chorus or keyboard scales. The synth is played with the touch pad, similar to a kaos-pad, where you play "virtual scales". Interesting is the multi-touch experience. Multiple fingers play multiple tones.

The app is 1,99 dollar. For people in love with singing Bebot, there are also shirts available over at Normalware or Red Bubble.
