Nothing , really . You just manage to wiggle your eyes in the right way to get both parts of the scrambled image in the right place , and the stereopsis starts to work . It ' s a pure depth perception kind of vision , which might feel a bit weird , so you get the never did that before tingle . <| sep |> Had something closer to your experience . I remember finally committing myself to going to a sleepover in grade school , and then crying on the phone to my mom later that night to come pick me up out of sheer anxiety . <| sep |> A drag route on 3 rd and 8 is not what we want . <| sep |> it ' s likely a draw <| sep |> Like in the clouds ? I want to be in the clouds . <| sep |> That ' s a stupid position to hold . In what way is it a slippery slope ? It ' s a largely private system of cameras which exist to deter thieves and other criminals . All it means is that if a crime happens in London there ' s a good to high chance that at some point the perpetrator was caught on CCTV , which makes it a lot easier to convict them . Do you think all these cameras link up to some central underground bunker where they all appear on a giant monitor ? That ' s not what ' s happening , other than traffic cameras and some high pedestrian traffic areas like tube stations I can pretty much guarantee that almost none of them are monitored live , no one ' s got the money , manpower or time to do that . And cameras used to catch people dressed in yellow ? Surely an easier way to catch people dressed in yellow would be to use your eyes ? I don ' t understand why people are so defencive of their privacy in public , by definition you don ' t have any privacy because you ' re in public . What ' s the difference between a camera that likely nobody is watching and the dozens of people that could witness what you ' re doing ?
