Head Up Display for a Multimeter

This is definitely one of the most impressive projects on Instructables. An engineer (a real one, not a software one ;-)) named Alain Mauer has built a special device that can be attached to glasses and enables the user to see data from a multimeter directly in their line of sight. This is important because when working with high-current devices and a large multimeter it is often difficult to have the device in a convenient location and constantly turning your head around to read the displayed data can cause an accidental short when your hand slips a little and the probe touches something it should not touch.
A detailed description of the project can be found here.
