I'm thinking about starting a button business in 2018.

Basically sell all kinds of button based controller systems.

Potential fields:
  * Productivity keyboards (keyboard emulation)
  * DJ controller (midi?)
  * VJ controller (midi?)
    * Olav?
  * Instruments (midi?)
    * Carrot fader

Method:
  * Online controller layout system, client can design their own controller.
  * Functions programmable through web interface or other system.
