What does a tech-savvy guy like Steve Jobs have in common with runway model Heidi Klum? Easy. They are both icons in industries that experience constant change; industries where one must remain two steps ahead of the game just to attract the smallest amount of attention: technology and fashion.

Leading fashion retailer, Forever 21, has creatively merged the two industries together to present consumers with a fashion first - digital runway shows. The retailer made jaws drop in Vienna, Austria on Monday as they executed the first of eight holographic fashion shows around the world. With the production help of space150, the show gave invitees the chance to see the latest fashion trends in a runway show comprised entirely of holographic models.

That's right. Holographic. It's more than just images on a screen, though. It's 3-D models walking an invisible staircase and disappearing into starbursts. Have a look at the fashion-forward 3-D show for yourself:

This isn't the first digital venture for this Los Angeles- based fashion emporium. Last year, Forever 21 introduced an interactive digital billboard in Times Square, where giant models interacted, in real time, with customers on the streets outside the store. Models snapped polaroids of the crowd, or picked people up, and dropped them into a store shopping bag.

So does this mean that Heidi Klum is out of a job and needs to turn to the Steve Jobs' of the world for financial support? Probably not. But it certainly introduces an interesting approach to the fashion industry and puts a new spin on digital branding.
