Picture of How to make a autostereogram
An autostereogram is a 2d image that when looked at properly, shows a 3d image.
This instructable will show the many steps to completion.

Step 1: Download and install a stereogram maker.

I used STMaker, a freeware stereogram creation program. It can be downloaded at:
(I am not the creator, just a user)

I installed it and opened it up.

Step 2: Choose your image

I used photoshop 7 for this, as well as an Instructables Robot silhouette.
The next few steps will be preparing the image to create a nice, rounded end image.

Step 4: Adding blur to "round it out".

I then used a gaussian blur of 3 pixels, to create this image. Go ahead and flatten your image and save it. I chose robot.jpg.

Step 8: View your artwork and save.

It'll pop up your piping hot stereogram for you to see. At this point, right click it and click on save, that way you can share it with friends.

In retrospect, I should have shaded the arms better, so they stood out.

If you want to see the image in 3D as you draw it, you can check out my iOS app, Depth Sketch.

This is pretty cool! I've never seen these on the computer before. Thanks for posting it. For the case of the robot, it might look more recognizable if you had left the silhouette alone in 2-D and simply let it sit raised above the background. I gotta try this. Thanks again!!

It works, but the shape of Robot is wrong, the perspective doesn't look right. Is this a limitation of the software, or just the way you've shaped the 2D into 3? L

It was my bad, I wish I had done more detail on the robot, all I got was a general shape. My artistic skills need a lot of work it seems!

So how exactly do you view them?
pick a point in the middle of the picture and stare at that point for about 10 to 20 seconds. the picture will become visible.

In I put a stereogram that I maked with a text editor.

With my method I can show 1 to 9 plain levels, but no curved surfaces. Anyway, it is not so bad.

cross eyed(or was it with your eyes parallel?) like you do with those 3d images which have two photos next to eachother
