I created a system monitor application for my FW 16 LED Matrix Modules. The left module shows the load on the 8 CPU cores with an outward spiraling pattern, the system memory consumption, and the battery charging status / battery level. The right module shows disk and network usage.
Source code is here for anyone that wants to use it, or just see how I used serial to send updates to the modules:
And here is a bad picture. The difference in brightness between the background and foreground elements in the display is better in person, and also configurable.
