89 Ways to Hide Your Face

While the 90 innovations in this slideshow couldn't be more different, they all successfully hide your face. My muse for this series was Wilson from 'Home Improvement,' Tim Allen's neighbor who always seemed to find a way to obscure his face with props like fences, garden equipment and power tools.

Design companies willing to tackle the multiple facets of masks will likely be rewarded by consumers eager to conceal or express themselves.
