Holograms and Pi

Built a simple device today which can project three-dimensional images to space from a surface.

The device has shape of a truncated square pyramid with transparent faces.

Place it at the centre of a display and play a video made specially for it.

It gives the effect of a free-floating object.

A 3-D video of a jellyfish being played on the device from a flat display.

It can give four different views of the object, if looked from the sides of the pyramid. We could see front, back, left and right of an object. But not any other view. It lacks a continuous 3-D feel as we expect with real objects. That is, if one slightly changes her point of view, the image remains the same, it does not rotate.

If, instead of a four faced pyramid and four images to project on them, one could use a shape with infinitely many faces and enough images to reflect on those faces, one might create a real looking object inside it. That is what I think.

Such a shape might look like a sphere. And I have a strong feeling that we are sitting inside a giant sphere.

That makes more sense when I find pi, the irrational number, in the most unlikeliest of places!

As if God placed it there so that we do not forget where we are and get lost!

Good idea mate! Thank you.
