Before you start

This post is a tutorial on how to work with “RIC” image files to create a simple game using the NXT display. For an example of what the finished game will look like and an introduction to RIC files, please see: Create your own games with “RIC” files.

To start making RIC-based games on the NXT, LVLM (LabVIEW for LEGO MINDSTORMS) must be installed on your computer.

I have used LEGO Mindstorms as a teacher since 1999, and have used it widely. For example, to measure noise in kindergartens, to have the students create lemonade blenders using small pumps connected to the NXT, and in process control with industrial equipment: pneumatics, industrial sensors, etc.
