Collecting cases where sound is generated from shapes and other graphic features.
"The Variophone was invented by Evgeny Sholpo in 1930 at Alexander Shorin’s Central Laboratory of Wire Communication in Leningrad."
"Unlike Avraamov, who shot still images of sounds on an animation stand, Sholpo used cardboard disks with circular images of combs with suitably shaped cogs rotating synchronously with a moving filmstrip. The advantages of the Variophone were in its flexible and continuous pitch control and vibrato. “
"It already incorporated one of the most crucial and necessary devices – a mechanism for the precise and continuous changing of the speed of rotation of the optical disk with the sound wave pattern i.e. a means of controlling the pitch with the possibility of synth".

"The technological basis of his invention was the method of photo-optic sound recording used in cinematography, which made it possible to obtain a visible image of a sound wave, as well as to realize the opposite goal - synthesizing a sound from an artificially drawn sound wave. "The method of Scholpo gives easier access to varieties of timbres. He doesn’t shoot still images of sounds on animation stand, instead using paper disks with a circular images of combs with appropriate shapes of cogs, rotating synchronously with a moving filmstrip. Exclusive benefits of Variophone are in flexible pitch control and vibrato".

To know more about the “Variophone” and other graphical sound synthetics inventions from the beginning of the 20th century in Russia the book “Sound In Z: Experiments In Sound And Electronic Music In Early 20th Century Russia by Andrey Smirnov” is one of the finest source of information.

Phono paper is a mobile application that converts drawings into sound. It is a format of graphical representation of sound based on the ANS synthesiser by Evgeny Murzin.
The sound is drawing in paper, than in real-time it is analysed throw the device camera and turn into sound.

READING MY BODY
"A sound controller that uses tattoo as a music score. "
"This is a special instrument that combines human body and robotic system into a single entity that is designed to automate creative process in an attempt to represent the artist and his instrument as a creative hybrid. The device consists of a railing with comfortable hand holders and two parallel, but offset from each other black lines’ sensors that move along the arm using a stepper motor. It is equipped with a 3-dimensional Wii remote controller that uses the OSC protocol in order to give a possibility of additional expression achieved by moving hand in space."

"DYSKOGRAF is a graphic disk reader. Each disc is created by visitors to the installation by way of felt tip pens provided for their use. The mechanism then reads the disk, translating the drawing into a musical sequence."
