The only thing constant is change ... isn't that what they say? One of the cleverest things I think a barista can do is coffee art ... drawing something in the foam on the top of your drink. I've seen people draw some amazing pictures ... and somewhere deep in my photo archives I have some wonderful shots of those pictures. But it looks as though this might be a dying art ... according to recent reports coming from the CES in the US, a company has invented a device which will be able to print images on the top of your coffee. The "stencil" will come in hundreds of designs and will be customisable for company logo, football team emblems, almost anything. It means the days of the leaf design on the flat white are well and truly numbered. And while this may be "progress", it does feel as though the world has somehow become a sadder place.
