 # User Interface dev notes
 
-The primary user interface is implemented in python 3 and targets a 240x240 color LCD for output and four buttons as well as a four direction joystick with another button as user input. It's a simple state machine that interacts with the musikcube api running on the same device. at the end of each state, the display's framebuffer is updated before moving to the next state.
