Yeah, it's a little bit "performance piece in a warehouse", but I think it's pretty cool. Motion-graphics designer Tim Jockel created this first fully 3D holographic fashion show for the German designer Stefan Eckert, which premiered in April 2011. Other designers have incorporated elements of holographic design into their runway shows, but this is the first to run without live models.

(For those who don't know, Pepper's Ghost is basically the effect used for the ghosts in the ballroom of Disney's Haunted Mansion. Also used on the Tower of Terror, and many theatrical stage productions).

Diesel also did a runway show that featured hologram-style effects, although they couldn't truly be called holograms.

But then, I'm not really in to fashion in the first place, so maybe I should be glad I don't "get it" and move on. ;)
