Dirty version of mbot LED matrix working with johnny-five

matrix.js

Thanks @ajfisher, I've added more functionality ... https://gist.github.com/geekscape/8e7e949c7e610c46ebfebad50c9ed9de

Now has the concept of a "screen", which you can clear, invert, draw points, lines (horizontal, vertical and other), rectangles (draw and fill) and circles.
