How do they make it appear as if the actual sun is off in the distance in 3D?

Did they invent the world's first 3D display that works at all angles without special glasses?

Are they lighting up a standard hologram in a novel way?

Are they using a special lens to magnify an incredibly tiny and incredibly bright light source?

Are they using a microarray lens sheet, similar to how lenticular products such as the Nintendo 3DS achieve 3D, except that it would work perfectly from all viewing angles?

Whatever the case, I don't care about the price; I don't care about the marketing fluff; I just want to know how it actually works. It's frustrating that we aren't allowed to know.

This is really cool! I'd love to have such a thing in my apartment. But since I just read the link on HN about removing ducks:

"Caution: the photographs on this site are real and unretouched. They are not computer renderings."

I just... don't really know why looking at real photographs is dangerous.

thanks for giving the main source :)
