While I agree, the term 'gigapixel image' seems to be off-putting for some. The notion of an image you could zoom into forever like some of the Escher works is interesting.

I say a 600 dpi color image (at scale) of an Italian balcony at some event at the Bellagio, it was pretty impressive.

Ken Perlin has done some interesting work on the subject: http://mrl.nyu.edu/~perlin/experiments/demox/Planet.html

It is a render of a randomly-seeded "Earth" that supports zooming. You can zoom in continuously to recursively expanding island formations. The formations are not random, in the sense that they are not decided on the fly. They are fixed based on the original seed and will stay the same if you come back to the same location. So the trick resembles displaying a map that takes up a huge amount of memory, even though that isn't really the case. As I recall the limits of the zoom have something to do with the width of floating point.

Apologies to Ken if I inaccurately described his demo. He usually makes the source available for download but I don't see how to get it here.

Wow, until now I had not thought to look up where the name Perlin noise came from, but wow! Thank you!

(for others, Perlin noise powers much of motion graphics effects today http://en.wikipedia.org/wiki/Perlin_noise, like such: http://www.flashandmath.com/flashcs5/fire/fire.html)

Hyper as a prefix is defined as exaggerated or excessive; I think it's extremely accurate.
