So what if mp3's and HDTV signals are missing some "natural" frequencies from the real world. What percentage of our lives do we spend listening to these signals? I would take this article seriously if people wore soundproof boxes around there heads 100% of the time, and these artificial signals were pumped into their ears constantly. This is not the case, so I have a hard time taking research like this seriously.
Someone should check this guy's funding - I would bet it's from the RIAA!
Dr. Dan Ashlock at Iowa State University has been evolving robots that push blocks around a 2-D world for some time now. Check out the BotWorld link on his research page for info.
On a side note, I did a research project for one of his courses during Spring 2002, where I evolved robots for Robocode that were effective in destroying human-programmed robots.
Guess what - we never see three dimensions either. We see a 2-D projection of 3-D space, and use stereoscopic vision (i.e. 2 eyes), motion, and pattern recognition to build a mental model of the 3-D structure of the world around us.
Using the data visualization technique known as the Grand Tour, one can visualize things in arbitrarily high dimensions. See the GGobi software for examples.
High-dimensional (or multivariate) visualization is nothing new in the world of statistics & exploratory data analysis. Check out the freely available XGobi software or the new GGobi package. For a 100% Java version, see Blue Orca.

Koza et al have been doing this for years via Genetic Programming (www.genetic-programming.com).

It's not a good reference, but tells a little about the project.
