This project is built on top of openFrameworks which is an excellent toolkit for creative coding in the C++ programming language. The work of integrating together libraries like OpenGL, OpenCV, and more is done for you, and the framework is ported to multiple platforms such as the PC, Mac, mobile devices, and recently the Raspberry Pi. To run the creepy portrait code you'll first need to follow these steps to install openFrameworks on your Raspberry Pi.
    The openFrameworks website has a nice overview for running on the Raspberry Pi that we'll use to install the framwork.

    Note: Be aware the initial installation of openFrameworks on the Raspberry Pi will take about 1-2 hours of unattended time while the framework is compiled on the Pi. Set aside some time before you continue further.

    To install openFrameworks on the Raspberry Pi, carefully follow the steps at the official installation instructions. In particular, don't miss the step to configure the GPU/CPU memory split to 128 MB before compiling. I recommend installing openFrameworks to the /home/pi/openFrameworks folder like the installation guide suggests. Also, you can skip the optional steps at the end to setup a cross compiler or DISTCC for faster compilation.

    Once openFrameworks is compiled, make sure you can compile one of the example applications by following the 'Compile your first app' step at the end of the instructions. Don't move on until you can successfully compile an openFrameworks application.

    Continue on to compile and use the code for this project.
