I get to work with some of the most advanced - and frequently complicated - technologies on Earth. But every now and then, something so elegant comes along that it absolutely knocks you over - not with it's amazing complexity, but with pure, purpose-build simplicity. The invention I have just seen is one of those sort of things. It is simple. It is effective. It is affordable. It does exactly what it is supposed to do. I have had one for the last 48 hours, and it is just amazing (I got mine on Wednesday evening while having dinner with Katie Couric, but that is another story...)

Can you figure out what it is?
