The anaglyph 3D viewing methods use 3D glasses (I recommend red/cyan glasses with the red lens on the left eye). You can get a pair of 3D Glasses for the cost of a self-addressed stamped envelope. The cross-eyed 3D viewing method is the best by far for color accuracy but needs some Training to master. If you don't have red/cyan glasses and can't master cross-eyed viewing, select the 2D viewing method for flat 2D images.
The 3D images will be just like you were there yourself. Enjoy!
