I created a quick project to start learning nodejs. To those that are unfamiliar nodejs allows you to write javascript for the server side. So I decided to write a small gui that plots serial data. The GUI itself is written in javscript/html and uses node-webkit to package it into a .exe file (or the correct package for your os).
This could easily be extended to visualize a lot more I/O from the launchpad, and given that the GUI is written in html/javascript it is really easy to create new elements.
Here is the source:

The repository includes the nodejs code as well as a simple Energia sketch to send a random value over serial.
