Take a deep breath and check out the new Air Piano, a German invention showcased this week at the Berlin Design Festival. Fashion Week Daily nails it as “a piano that Purell addicts will love”. Standing in front of the “keyboard” (welcome to another technology-induced crisis of vocabulary), waving your arms around slightly in front of you, the “performer” looks as though he’s doing the washing up. While the Design Blog valiantly attempts to describe how the technology works – sorry, how to actually play the Air Piano – at the end of scrolling through endless pictures and this YouTube video, I’m still stumped as to why anyone would want to play the instrument. There’s also that pesky pre-requisite of having to understand notated music in order to know where exactly to swing one’s arms above this technological marvel. Unless I’m missing something, which in the realm of new technology is more than likely. Suggestions?
