For a public art display that would probably get folk's attention, billboards and ads on buildings that mimic those in the movie They Live.
As you drive buy, you'd see a pretty girl on the beach opening a refreshing soft drink, but as the angle changed so would the picture, showing instead in dark block letters "CONSUME". An investment firm might change to "MONEY IS YOUR GOD", a politician advertisement to "OBEY", a clothing line "CONFORM".
I think as a art project you'd at least get the people looking, maybe even start a dialog. Those always turn out great, everybody respectfully works out their differences, come up with solutions and sing kumbaya while holding hands. That's always nice.-- doctorremulac3, Sep 21 2023 This... https://live.static...08_4c46b9b04d_b.jpg [doctorremulac3, Sep 21 2023, last modified Sep 22 2023] turns into this as you drive by... https://www.sott.ne...7/full/theylive.jpg [doctorremulac3, Sep 21 2023] using this. https://www.youtube...watch?v=8p_Z9CAr5OQ [doctorremulac3, Sep 21 2023] https://www.famousc...lp-abused-children/ Lenticular effect that's aimed to be more visible to children.
