Amaze your friends by sending them secret messages, hidden in 3D stereograms.
A 3D stereogram (SIRD) is a seemingly meaningless image with a repetitive pattern. But with some training you can reveal hidden 3D shapes within the image.
With si3D you can create your own 3D stereograms. Draw shapes or text with your finger and let si3D convert them into 3D stereograms.
Share your generated stereograms with your friends through e-mail, Facebook etc.
