![]() In the novel, Heinlein presents an interesting solution to the problem of presenting three-dimensional views without using special glasses. Note that this was written before anyone knew what a hologram was.
As an aside, this is also probably the first reference for the idea of a screen saver. One of the earliest implemented screen savers was an aquarium scene.
There is an earlier mention of stereovision in The Star Beast, published in 1954; this quote is more interesting.
It is important to note that a sterovision tank is different from a "3D" movie or flatscreen projection. The first 3D movie is probably Power of Love, released in 1922. It used the anaglyph process, which involved shooting two views of a scene (each in its own color) and then combining them. The familiar red and green lensed glasses were used to create a stereoscopic effect. The famous movie House of Wax really kicked off the 3D movie craze in the early 1950's.
