Here are some of the things that I do and make for fun. Things I do professionally (CTO, Head Geek stuff) can be found on my LinkedIn profile.
Recently (Nov 2012) I made a website which posts your favourite albums (daily, weekly, monthly) from Last.fm to your Twitter feed. - Scrunched.fm.
I'm currently building a website which finds correlations between your online (and offline) activities. - Correlation.me. (under construction, Spring 2013)
I have been known to troll my friends... http://shardholder.org.
