"Ototo–a pocket–sized circuit board in the mold of the Arduino and MaKey MaKey that was was designed to be a 'musical invention kit' and helps kids build bespoke electronic instruments without writing a line of code or burning a single finger on a soldering iron. It can play music out of the box with the 12 black and white triangles acting like piano keys and a surface–mounted speaker emitting sound, but it's killer application is the ability to create outlandish orchestras by connecting it to funky objects with alligator clips. Plants become percussive instruments, sauce pans become a drum set, and even simple pencil sketches can produce unique sounds when tapped."

"This new instrument, known as the 'Grand Letar,' is the invention of Letritia Kandle shown here playing it. She designed it and had it built specially for her. The instrument as 26 strings and a lighting effect that is very new and novel, being he first instrument to change color while it is played.
The string grouping used on the I 'Grand Letar' which has complete harmony has been studied and developed by Miss Kandle over a period of six years, the development being derived from an eighteen string triple–neck Hawaiian guitar which he also designed and had built for her. Miss Kandle has played coast to coast programs over NBC and has done electrical transcription work for RCA. She also has had her own string ensemble for which she did all the arranging.
Miss Kandle demonstrated this instrument at the recent manufacturers convention in New York City."
