I'm in a boat similar to Kristta. Indeed, roughly 35% of the population is in a similar boat. Part of the reason for so many different variants is they are all trying to overcome something to do with inability of people to see the effect. It's kinda sad. I like 3D stuff -- I can see most holograms and holographs fine, but stereoscopic anyting is pretty much lost to me :( last time I took my kids to see a movie in 3D, we bought all the special stuff for them, but then I left and read a book.

thou and I, my friend, can, in the most flunkey world, make, each of us, one non-flunkey, one hero, if we like: that will be two heroes to begin with. (Carlyle)
