With companies like Sony and Nintendo pushing 3D like it's their jobs, it's easy to forget that there are some people whose brains simply can't process the combination of two images. An interesting blog post over at Grouvee explains what looking at 3D images is like when they don't appear 3D, and whether any enjoyment can still be squeezed out of Super Mario 3D Land.

"For as long as I can remember, I’ve been one of the few people who are incapable of seeing 3D images," they write. "Sitting through James Cameron’s opus about blue cat people trying to save a magic tree not only gave me a headache, it temporarily robbed me of my ability to see depth of field. I had to have a friend drive my car home."

So what about the 3DS, which uses different tech to create the 3D effect? Still no luck. But "was the game still enjoyable? Yes, but with a greater degree of challenge."

Can you see 3D images, or are you one of the minority who can't? How does the 3DS look to you? Let us know in the comments or on Twitter.
