application scenarios
the conceptually most interesting application is the stationary use of the object when it is displaying content that is critcising other messages in tits surroundings.
for example, placed on an ad for a supplier of cheap nuclear electricity, the device can show a radioactivity symbol.
in order to see the symbol, people have tho shake their heads in front of the ad, so they are performing a gesture of negation. this way, the observer is included in the setup and completes the statement by trying to see the content displayed...
the initial spark for doing so is the subconscious movement of the human eye, called "saccade" which reveals the content very short but noticeable somewhere in the observer's field of vision.
another scenario would be to place the device near a race track, where people follow the cars with their eyes or even a camera. criticising the enormous amount of emissions produced, the writing "CO2" is displayed.
as a subtle warning sign for speeding drivers, the device is placed next to a highway showing crosses. if one passes by fast enough, he will see them and is reminded of the risky nature of his current activity
(in the last two cases, typography can be used, since the direction of movement is known. in the headshaking scenario, the use of symmetric symbols is imperative, since on changing the direction of eye movement, the content is flipped horizontally)
