The crosseye stereo effect is pretty decent with this one. Images taken about 20cm apart.
For those unfamiliar with this form of 3d, view the image as large as you can and still get both frames on screen.
Sit about 30cm away from the screen and go slightly cross-eyed until you get a third image in the middle. You may need to tilt your head slightly until it's lined up correctly with your head orientation.
Now, carefully focus on the middle picture. You need to concentrate and relax, but it becomes easier with practice.
You'll know it if you manage to do it ;-)
