Internet navigation browser plug-in maker Cooliris, which lets users “see” media on the Web in a more visual manner, has gotten $15.5 million in additional funding from its investors.

The new round includes Kleiner Perkins, Cooliris’s initial investor, as well as DAG Ventures, the Westly Group and T-Mobile’s T-Ventures.

Cooliris had already received $3 million two years ago from Kleiner.

The Palo Alto, Calif.-based start-up is also releasing the latest upgrade to its 3-D “wall” software out of beta, which adds more online content from around the Web, including from social-networking sites like Facebook and from a user’s own hard drive.

The trend toward making the Web browser look like a television screen and navigating information more visually is increasing all over the Internet, from video services like Boxee to visually-oriented search services like Searchme.

“We’re trying to allow users to discover, navigate and consume more of the Web in the same amount of time, using visual means, than people do now through text links,” said Austin Shoemaker, Cooliris co-founder and CTO in an interview last week with BoomTown.

Launched last year with a plug-in called PicLens, Cooliris said that its software had been downloaded 10 million times and that it has three million active daily users. It also has a popular iPhone version of its software.

And, like all things in mapping, the best way to see slopes is now in 3-D, the technology that is going to become more and more prevalent on the mostly flat Internet in the years ahead–and well beyond the more obvious applications.

Along with touchscreen technologies that will come much sooner to the general computing experience, 3-D is a feature that adds amazing depth and resonance to the online experience, especially as more information is added over time.

If you don’t think so, here are two of the 23 slopes that Ski.com has up now, for example. While they do not show falling snow (yet!), click on through for a very cool experience of looking at and manipulating a mountain before schussing down it–or, in my case, tumbling down it.

At the SIIA Information Summit yesterday, New Yorker writer Ken Auletta, who recently did a piece on Google, noted:

We’re in an engineering culture. You couldn’t put a [Rupert] Murdoch or a [Michael] Eisner in charge of a company like that. It’s been tried. Terry Semel led Yahoo. I just spent some time with Google engineers. I couldn’t understand a thing they were saying. I don’t think [Semel] understood the engineers’ language, so he couldn’t challenge them. I suspect that’s one reason he didn’t last.”

Auletta is right, and it is an increasingly interesting issue as we move forward with the hyper-digitization of content.

While, for example, the use of online video increases exponentially, how big an audience can be created for any one property without the kind of intense programming and marketing that the entertainment industry is famous for?

On the other hand, is an increasingly massive reliance on e-metrics–the ability to minutely tell and even predict what an online audience wants by their clicking and being perfected by engineers at widget companies like Slide–the right direction?

I have no idea, but the delta is one that needs bridging.

WSJ Online’s Andy Jordan reports on three-dimensional printing at home, called Fab@Home.

In other words, someday you could “print” your own cellphone or even a robot that could walk out of the printer. And, it’s possible that device can even print food. Yum.
