The company I work for rents office space in a tower downtown. The elevators have video screens running advertisement loops. There&#x27;s no audio, at least, but it&#x27;s still <i>incredibly</i> irritating to have advertising pushed in my face when I&#x27;m just trying to get in or out of the office.<p>I bought a roll of translucent contact paper which has a diffusing texture and cut it into squares. When I leave work, I take a square with me and cover the screen in the elevator on the way down. The advertisement video becomes unrecognizable under the soft kaleidoscope effect. The building staff is pretty quick about taking them down again, but it still makes me feel good to fight back.
