Ok this looks pretty cool, and from the reviews are really good. Might be time to make my first Kat Von D makeup purchase.
Kat Von D Shade Shifter Eyeshadow
What it is:
An innovative eye shadow with a chameleon-like, color-shifting shade.
What it does:
Change your view and change colors with this bold, multidimensional shadow. Adorn your lids with the lustrous pigment and watch as the hue alters, depending on the angle of view and available lighting. Activated by water, one swipe gives you highlighting, contouring, and deepening possibilities for a sensual, dramatic look with a duochrome effect.
What else you need to know:
This shadow comes accompanied by a large flat-sponge brush, specially designed for application technique.
