As well as blogging and tweeting, I also make stuff...
Chromoscope
View the Universe in different colours in a web browser. Who needs Google or Microsoft when you can make it yourself with Gaffer tape and HTML?
LookUP
A simple site that takes the name of an astronomical object and finds out what and where it is. Get results as a webpage, XML or JSON.
365 Days of Astronomy
I help with the podcast of the International Year of Astronomy 2009. I automagically create the weekly edition using Perl, Sox and (shudder) IDL.
Jodcast
A twice-monthly astronomy podcast featuring the latest news, interviews and the night sky.
SpaceBuzz
A toy I made to display the currently popular tags being used within the astronomy blogosphere.
.Astronomy
The most exciting astronomy-internet-related conference of the year! I was on the organising committee for the second .Astronomy in Leiden.
Astronomy Media Player
My attempt to bring all the astronomy podcasts into one place. It has since been superceded by Portal to the Universe.
