Have you experienced 3d on high end 3d LED television in shopping malls and electronics stores but cannot experience the same at home obviously cost being a major factor for 3d television and 3d glasses. The most important factor being 3d is not yet standardized and you have multiple viewing options from different companies.
YouTube has enabled 3d viewing but not has publicized much of this feature in fact there is a Fashion tv 3d channel running in beta. YouTube supports many 3d format including the old and famous anaglphy technique which makes use of colored glasses i.e. red and cyan to create a stereoscopic effect. HTML5 stereo view allows you to view 3D video on YouTube which currently supports NVIDIA 3D Vision and the drawback is doesn’t support most of the systems. There is method for 3d on YouTube even without 3D glasses but you will have to go through serious squinting of eyes to watch it (crossed eye,parallel,mirror split techniques not worth a try).
