Virtual Wallpaper

Why bother with sticking stuff up and then taking it down or painting it over when you can simply flip a switch and create an infinitely variable wall tableau?

The quick–and–dirty approach to wall decor.

Mathmos has created Surreal Wallpaper.

You put a disc into a projector "and watch the continually shifting patterns as it spins," wrote Ernest Beck in an October 6 New York Times story.

The images are up to three feet in diameter and appear in changing combinations of red, blue and green.

A projector with a disc is $135 at Fellissimo Design House (10 West 56th Street in Manhattan; 800-565-6785).

Additional discs cost $33.

Note that the discs are made in limited editions of 900 so don't think about it too long or you'll be playing — as we used to say on the sandlot baseball field — left out.
