+I've had this [MatrixPortal M4][m4] from AdaFruit for a little while now. It's a
+fun little bit of hardware. Easy to hack on with the Arduino IDE. AdaFruit have
+published a bunchh of useful libraries for doing fun things with LED matrix
+displays. Here it is running a metaballs simulation on a 64&times;64 matrix
+display.
