Here is Bliptronics 5000, a LED synthesizer that is played with a gird of glowing buttons. Each row of vertical buttons represents the notes in one octave. Push a button to turn on a note, push the button again to turn off a note.
The device allows users to set tempo from 60 to 180 in 20 BPM increments and offers 8 different old-skool synth sounding instruments to choose from. It creates sounds using FM waveform synthesis and comes with built-in speakers with headphone jack and line-out jack. Users can also chain multiple units together and create more complex melodies.
The Bliptronics 5000 synthesizer requires four AA batteries to work. It is priced at $49.99 at thinkgeek.com.
