Introducing the Infiniwand

Karen's company is the leading manufacturer of specialty items and gadgets in the world. Renard's department, R+D, is the main area for the development of such items. Karen helps out occasionally in the creation of some of the products. Nuke is no longer allowed in the building after he smashed half the department's computers because he was convinced they were infringing several of his copyrights (when, in fact, it was the other way around).

This particular item allows the user to alter the color of fur, hair and eyes simply by exposing the area repeatedly to the special kind of light emitted by the wand. It can also do patterns and such if you're computer savvy.

It's mainly used by the team for disguises, camouflage and such.

Here Nikki is using to to change colors from Orange to White.
