What invention has made you smile recently

Roughly about two months ago, I had a chat with some friends about inventions that I believe have wowed the world. Telephone, internet, bulb and keyhole surgery topped my list of mentions.
I thought to myself that there has not been any recent invention asides mobile phone that took the whole world by storm.
I saw this short clip of  this 'Kazbrella' and I was glad people still have their thinking caps on and research and development is still very much alive as regards invention.

Please listen to this inventor and hear how the idea came about.

You never know. You might become the net inventor too ;)
