Wall art adds dimension to dwellings, distracting guests while you do one last sweep for any overlooked bits of superhero costuming. Keep your identity safe with today's Groupon: for $39, you get $90 worth of vinyl wall-art stickers from Voilà Stickers.

Using eye-entrancing trompe-l’oeil technique, Voilà Stickers designs vinyl wall adornments including cityscapes, cultural icons, and modern graphics. Thin and stretchy, washable stickers bend around interior corners, mouldings, and unicorn wall sconces, clinging to any clean surface for at least five years (three years on exterior surfaces). Refrigerator doors transform into London Underground entrances ($18), and an arch of the Eiffel Tower ($88) transports dining rooms to the banks of the Seine. The cult collection honours icons such as Michael Jackson suspended in his gravity-defying lean from "Smooth Criminal" ($38) and Edward Scissorhands hugging a tree that just complimented his branch-like fingers ($75). Each order includes a squeegee for smooth, bubble-free installation, and stickers easily remove and, depending on the texture of the surface, re-adhere for a sojourn upon a new surface.
