Do you know what a stereogram is? It is a picture where you see only a pattern at first, but when you squint or see in the far, forms will pop-up (in 3Dimentions) from the image. If you have never seen that I would advice you to take your time and try to see the hidden information of the pictures. Bigle 3D is a stereogram generator or SIS (Single Image Stereogram). To create you own stereogram, give a background, and a greyed image that contain the 3D information: So more an area is dark, so more it's far away. Everything is realised in a Wizard. You can save your stereogram under the main images format (BMP, PNG, JPG, TIFF?) and open even more types of images to create them. Follow the link and free download Bigle 3D now.
