ROP is a simple and extensible framework to display a set of art demos on an LED array (such as FadeCandy) or in ASCII Art on a terminal, and includes a 2D drawing primitive implementation.

Some art have problems with non-square buffers. I'm not sure if this is an issue in buffer, DiamondSquare, or terrian specifically, but here's a trace for you:
This is with a 25x50 pixel array ( https://github.com/zestyping/openpixelcontrol/blob/master/layouts/wall.json )

Opening up a new terminal window in iTerm2 defaults (for me) to 80x25. When I run art.py in that window the program immediately exits without any feedback. Looking at at art.log

The terminal window needs to be a bit bigger so it can display. Let's get a better error message to the user.
