Being able to mimic the Sun's 'perfectly white light' is brilliant. Many people find CFL's really annoying.<p>Almost as cool though is the fact that it can easily be built in any shape desired, as it sounds like you run a change through a surface instead of having a specific light-generating element.<p>The example they give is of a 2x4 'panel' replacing CFL's in offices, but could imagine some fantastically cool applications of this in interior design.
