Don’t blink!

From Thinkgeek:

Each Weeping Angel Christmas Topper is made of space age plastic and fits over the very top of your festive indoor plant (or plant simulacrum). The Weeping Angel has her face covered, averting her eyes from your gaze. But if you blink… if you dare blink… who knows what will happen. You might end up visiting Ebenezer Scrooge and the Ghost of Christmas past. The Weeping Angel Christmas Topper is all about showing the world you love Doctor Who, while taking a big risk that this Angel is just decoration.
