Happy Birthay Smiley

The digital smiley emoticon celebrates its 25th birthday tomorrow.

Smiley was 'invented' by Carnegie Mellon professor, Scott E. Fahlman, during a discussion about the limits of online humour and how to denote comments meant to be taken lightly.

Happy Birthday Smiley, you brighten my day on a regular basis, even if half the time I accidentally make you wink.
