Graphics, User Interfaces Within the last few days we read the news about Apple's Siri AI personal assistant, and about a brain implant that lets monkeys control virtual limps & feel virtual objects. I believe that if someone is to also combine a few more technologies (e.g. high-res eyeware, appropriate operating system changes), we will be looking at the next user interface revolution, after the inventions of the computer mouse and touch interfaces.

See, what I was saying ;) - even technology enthusiasts, and such, not realizing about this fairly old[1] stuff (easily older than you, Thom) ...so what hope there is for the general public, whose "imagination" is shaped by cheap popular scifi productions?

1. Old in terms of recent technology progress; the implementation I randomly found on YT not really being so ground-breaking as they claim, it mostly "just" seems to revolve around being a decently marketable product. Any self-respecting physics department probably has some holograms, and there are a few ~commercial labs around the world that make them (contact one, Thom? Maybe they'll even have some defectively developed one - which could just look weird in part of the "image" or under certain viewing angles - but probably still impressive, clearly with depth[2])

2. Yes, in holograms that is essentially a real depth, they are about reproducing how the light would really behave if the plate had some insides.

PS. BTW, you can easily do a basic, but still fun imitation of sorts (one which relies more on psycho-visual effects in how our brains are wired to see ~faces than on actual scattering of light in a "proper" way), if you have a printer! ;)

Hollow-face illusion http://en.wikipedia.org/wiki/Hollow-Face_illusion & three dragons to print out http://www.grand-illusions.com/opticalillusions/three_dragons/

Actually, inspired by how one preschool-theatre costume (of a... cat; with proper ears) supposedly induced a panic attack in the kitten of my buddy, I essentially reworked the dragon once, to be more "danger! Possible unknown big cat!"-like. Yup, my cate became... nervous.

(quick Google search for the above Wiki page even revealed one with a cat design http://allgraphical.blogspot.com/2010/10/paper-craft-illusion.html
...I can't vouch for how convincing it is, though)


Bonus points: place a large version in a street-facing window ;)


Then there are also some software toys like this DSi game http://www.youtube.com/watch?v=h5QSclrIdlE which, essentially, partly simulate - to one viewer at a time - roughly how a hologram would feel.
