Abstract
A tool, such as a digital level, includes displays on top and side surfaces of the level. The top surface display provides an additional visual means to communicate the orientation of the level by emitting any of several visual signals. A processor in the level determines a measured orientation of the level and sends a communication signal to the top surface display to emit a selected visual signal based on the measured orientation.
