Level Tool is an activity to check the inclination of a surface with respect to ground.
Note: You need an OLPC XO-1.75 or XO-4 laptop to use Level Tool.
Level Tool uses an accelerometer to detect the inclination of your laptop with respect to ground and displays it in a well defined circular grid.
Level Tool can also share with other laptops using collaboration, so that the inclination of a set of laptops can be seen at the same time.
The Level Tool activity is available for download from the Sugar Activity Library: Level Tool
The source code is available on GitHub.
