On last week's Gizmodo Shooting Challenge, submittors were challenged to create photos that could be seen in 3D, simply by refocusing the eyes to merge two appropriately placed white dots.
Having trouble? Here's how you do it, from Gizmodian rick23:
- Look at the white dots so that they look like, er, two white dots.
- Relax your ocular muscles so that you get double-vision (you can do this, right? I mean sober— everyone can do it when they're drunk...)
- You should now actually see 4 dots— two on the left and two on the right (you have to use relaxed peripheral awareness to do this; if you try to focus on anything, the two dots will snap back to simply being two dots).
- Gently nudging your de-focused imaging, try to bring the near left and near right dots into alignment, thus getting one dot in the middle and one dot each on the left and right. (This is kind of tough, and I'm probably used to it because my department's admin puts up those Magic Eye posters on the bulletin board.)
- Once you've managed (4), simply allow your gaze to float down to the picture below. You should see (peripherally) a picture on the left, and picture on the right, and, more clearly, a picture in the middle. The middle picture is in 3D.
