We've all been to at least one 3-D movie experience in our lives, (and if you haven't, well shame on you.) Anyway, 3-D generally required the use of 3-D glasses. Even the first generation 3-D televisions required expensive glasses in order to function. Now we're at the point where we don't need the glasses. Toshiba has introduced a television that doesn't require the glasses in order for things to appear 3-D. Go to the mall in Ithaca (Pyramid Mall) and near the SPCA and AT&T there is a television display where it looks 3-D without the glasses. Honestly, I think it's terrible. Within 5 minutes of standing there and trying to watch the TV I got a headache and had to walk away. It's so distracting. I personally think 3-D is cool for special effects or for things popping out at you (Like Harold and Kumar's 3-D Christmas). For regular television it's ridiculous.
