So, I know it's not Friday, but here's something fun I just discovered recently: Emoji - a character set of emoticons that originated in Japan and are beginning to settle down into an Internationally agreed standard.
How did I stumble across this? Well, I've known for some time that my iPad and iPhone can use different keyboard layouts but what I only just discovered is that one of those keyboard layouts is emoji.
This means I can type a range of emoticons directly into anything that can take text. Of course, I'm not sure how it will look outside the iPad. Apparently, it is built into most Japanese handsets, and as a result, many other handsets too including iPhones and Windows phones.
So have a look around in the settings of your devices and email programs to see if you can do emoji too.
