DimSim
this device was a portable holographic projection unit that projected a "shield" of darkness over the wearer's face. The DimSim looked like a large hand that wrapped its fingers around the front of the skull. Each finger held part of the holo-unit, and heled maintain the shield. This device allowed the wearer to see out beyond the shield with minimal interference, while others were unable to see the wearer's face. DimSims found a widespread use among thieves and hijackers during the end of the Galactic Civil War and into the age of the New Republic.
