Start and Stop Pi Eyes from Within Another Program

[DevMiser]

Thank you for this great software. Pi Eyes starts on boot. I instead want to be able to start and stop the eyes (turn them on and blank the screen) from within another program (presumably using subprocess). I know to comment out the lines in the script /etc/rc.local to stop Pi Eyes from starting on boot. But can you tell me what I need to put in my other program to start and stop Pi Eyes? Thank you.

Alternatively, is there code that will turn the oled display on and off?
