This is how I do it. The problem is that this inverts the depth map, because your right eye sees the left eye image and vice-versa.

To properly view them, you need to go wall-eyed, by focusing on something behind the screen. This is something that I have not been able to do yet.

The other problem with the cross-eyed technique is that it can be hard to maintain a sharp focus on the 3D shapes. And it will really hurt after a while.

It's a good technique if the repeating strips are really wide. On my screen at least, the strips here are pretty narrow, so it should be relatively easy to converge your eyes correctly.

Having said that, I don't know if this script is resolution independent, so it's possible that on some monitors the strips are a lot wider than they should be and that could be giving people more trouble.
