Hi @strawhat thank you for sharing your experience with those "3D screen and glasses". I am a 3D artist and when i hear peoples speaking about the 3D technology in theaters and on TV screen I always want to step in and tell them this is not 3D this is just a marketing name given to a 2D picture or film with some relief added to it with the glasses. If a movie is in 3D the audience will have to wear some kind of immersion helmet so everyone in the audience can go where ever they want into al the scene of the movie (like a 3D game with an immersion helmet) In this case and only this case we can say 3D experience. Marketing peoples have put the 3D name on this 2D technology because when it start 3D was all around even in the name of snacks. Also i have been a few time to theater look at some "2D relief movies" and i agree with you the glasses are very annoying after a little time i always want to take it off. Thanks for your post i follow you now and ^
