So, here is how it went. A recent issue of Playboy offered for "free" a pair of 3D glasses. Your garden variety red-cyan 3D glasses. And I thought, hey... I don't "read" that imbecilic magazine but I never used a pair of those before so why I shouldn't spend 4$ on something completely useless? And as it often happens, my instincts got the best of me and crushed it to bits and I bought the magazine. I go home very happy that I can finally see for myself what the hell is it with these 3D glasses... and lo and behold... I can't see a damn thing. Now, I understand that you can't provide a real 3D effect from a 2d picture... but come on. I tried dozens of them and the only difference when I put the glasses on is that I see the image clear. Well, thank you, but wouldn't have been easier to print the image clear in the first place? And also thank you Playboy for the headache this got me. Now, the default question: Is there something I do wrong? Do I have to actually believe they're 3D in order to see them 3D?
