This is a replica Icon worn by almost all of the characters depicted in the 1994 animated series, ReBoot.
The device allowed the characters to alter their outfits to match those of the NPCs in Games the Users would initialize within Mainframe so as to participate unhindered in the Games so they could beat the User and save that part of the city and it's inhabitants from being derezzed.
Included are three variants - a black/white one for regular Sprites, a black/gold one for Guardians, and a purple/green one for Megabyte's Sprites. The base object is white/white, so you can modify the colors as you please.
The Icons are four Prims each, but only 2LI. They are made of Prims, so stretching them shouldn't pose any burden to your land.
NOTE: This item is not scripted and will not change your outfit without alteration.
