Stereograms by Scott Pakin

Here are a few wall-eyed autostereograms I drew. Enjoy!

	Apple and Orange	I was curious if I could produce an autostereogram containing colored objects—something as close as possible to a true-color autostereogram. In Apple and Orange I tried to color the apple red, the orange orange, and the shelf they're sitting on brown.
	Wooden Chair	I was wondering if it's possible to produce an image that's simultaneously an autostereogram and an anaglyphic stereogram (to view through red-cyan glasses). Wooden Chair is my first attempt to produce such a unified stereogram. The anaglyph image looks good, but I wish that the autostereogram were crisper.
	Beach Ball	This is an experiment in including (faux) transparency in stereographic images. In Beach Ball, note how the ball has red spots in front and purple spots in back, and you can see the purple spots through the transparent red spots. I like how this image turned out.
	Pottery Sale	This image represents an attempt to combine a wallpaper stereogram and a random-dot stereogram. In Pottery Sale, the pottery is a wallpaper stereogram while the back wall and the front of the table are both random-dot stereograms (in name only; the back wall is of course a tiled pattern).
	Memories	I wanted to see if it's possible to use more than one tiled pattern in a single image. (Answer: yes. ) Notice how in Memories, the pattern fades from an alphabet in the upper-left corner to raspberries in the upper-right corner to dice in the lower-right corner to roses in the lower-left corner.
	Who's on Top?	Let your eyes diverge when looking at this wallpaper stereogram. You should see the array of cubes floating above the array of spheres, which in turn are floating above the patterned background. Rotate the image (or your head) 90°. You should now see the array of spheres floating above the array of cubes, which in turn are floating above the patterned background. I'd love to perform a similar trick with a random-dot stereogram but don't know how.
	Bowl of Gems	Like Pottery Sale above, Bowl of Gems combines a wallpaper stereogram and a random-dot stereogram. However, Bowl of Gems places the wallpapered objects (gems) on top of the object represented by the random-dot stereogram (a bowl). Not only that, but different gems appear at different depths based on the depth of the underlying bowl. (That took a lot of trial and error, incidentally.)
	Empty Table	In Empty Table I used a single tiling pattern throughout the stereogram but varied the brightness. The result is an image that includes both illuminated and shadowed regions.
	Scattered Shards	I struggled for a long time to find a way to produce a stereogram that can be horizontally and vertically tiled. All of my attempts ended up being flickery and hard to focus on. Eventually I gave up trying to tile arbitrary objects and limited myself to abstract shapes, which are a lot easier to deal with. You can see the result of my efforts in Scattered Shards.

	Lovesick	I was aiming for minimalism here—just a few dots on a solid background. Unfortunately, making the 3-D image sufficiently clear required a lot more dots than I had intended. The good news is that I found that I could create a nice transparency effect à la Beach Ball (above) by superimposing two stereograms: one showing the top half of the object and one showing the bottom half of the object.
	Winter Scenes	This may seem like an ordinary stereogram. However, it's really a subtle experiment with color. Once you've viewed the stereogram, try converting the image to grayscale then normalizing the gray levels. The result probably isn't what you'd have expected.
