 ##  Basic idea
 
-This tool was initially made for projection mapping of a large space, which required multiple lasers. Received lines are assumed to be in world-space coordinates. The space is mapped to distinct laser DACs by means of homography/corner-pinning and various geometric correction parameters.
+This tool was initially an adaption of the [laser_frame_stream_gui.rs example code](https://github.com/nannou-org/nannou/blob/master/examples/laser/laser_frame_stream.rs) to enable projection mapping of a large space, which required multiple lasers. Received lines are assumed to be in world-space coordinates. The space is mapped to distinct laser DACs by means of homography/corner-pinning and various geometric correction parameters.
 
 By using ZMQ as input, the mapping of the lines is decoupled from the generation code. In my own setup ([trap](https://git.rubenvandeven.com/security_vision/trap)) the lines are generated by means of a sequence of Python scripts.
