Scientists over at UC Berkeley are exploring metamaterials that achieve negative refraction of light in the optical frequencies. So, we’re finally getting close to really tricking those fantastic lenses known as our eyes.
Invisibility cloaks will definitely appeal to the voyeurs and teenagers sneaking out of the house. Still, regardless of everybody crashing into each other on the streets (unless our PSM – Personal SONAR Manager – keeps us at a safe distance from each other – check out this piece of design fiction) I can think of some other advantages. Don’t want that car in red, but blue instead? Just change the ol’ angles of refraction. Next week you decide you like black? Tune it again to suit your mood.
Will we stop believing what we see? Or can we change what we believe when we can change what we see? And will things get more sparkily?
