Are you able to see the fun and striking 3D in the old Viewmaster viewers? Or in the more modern 3D theaters or virtual reality viewers? If so, and if you can see double when you willfully cross your eyes, then you have a built in, free of charge, virtual reality viewing capability!

The videos herein are not 3D, but the photos are crossed (meaning that the photo for your right eye is on the left, and for your left eye is on your right) stereoscopic 3D. Scroll down to look at one of the photos and cross your eyes. You will see 3 photos: the one on your left will be seen by your left eye only, the one on your right by your right eye only, and the one in the middle by both eyes. Concentrate on the middle photo and allow your eyes relax focus while continuing to keep that middle photo "together." It may take a little practice, but you will eventually notice the same striking 3D appearance that you get with some of the expensive virtual reality goggles!

You may find it tiring at first, but it will become easier and more relaxing the more you practice it. This technique, when practiced regularly, can also be used to make the visual system more efficient, and may lead greater comfort during intense visual work tasks.
