Even though Berkeley is lush enough by itself (in 1993 at least), it has its little parks like People’s Park or the Rose Garden. I happened to live right below the Rose Garden and could, like the occasional deer or burglar, just hop over the little wall.
One of my (these days somewhat neglected) hobbies is to take stereo images, and the gorgeous roses were patient victims. All these pictures were taken hand-held, and they are supposed to be viewed cross-eyed, i.e. the image for the left eye is on the right. 
The rule of thumb for taking stereo images handheld was to choose a landmark point at the center, take a picture, take a step to the left, recenter, and take a second picture. This works very well for average street scenes without moving objects, like MacArthur Station below.
Our brain is more than happy to ignore little inconsistencies. If you do that with flowers, you will of course end up taking an entirely different picture. So you have to scale down and move just a centimeter to the left. This is still pretty wide and gives these flowers the appearance of rather large objects. You can do the opposite by taking images from a plane and wait 10 seconds between the shots. This will give the stereo image the appearance of a toy landscape. I’ll dig out an example when we come back from Mexico (early 1994, that was).
Finally for today, a stereo image of Hermann Karcher, also from 1993, thinking about Helicoids.
