I have worked on a variety projects in 2009 and coincidentally they have all been Mac OS X & iPhone based.
iPhone
I did some work over the summer for an agency in London called RPM. I worked on the Stella Artois bar locator. The app has since been removed from the app store.

Angela Patchell Books
I worked closely with Angela Patchell on the first iPhone application for her specialist publishing company.
Guardian Media Group
I had worked on an media content management system for the Guardian Media Group while working for Met Film Post Ltd.
It was quite a detailed project to provide a technical solution for the work flow for getting video shot on location and in the studio into a media repository and then edited using Final Cut Pro.
Much of the system was build using OO Perl. There was a custom metadata editor for OS X created called the "Ingest App". This application made extensive use of the QuickTime API and CoreData to represent the Meta Data in the application's state.
Quartz Composer
In 2009, I have worked on 2 Quartz Composer projects:
Project MINDTouch - Smart Lab, East London University - an interactive performance piece using Bluetooth and Quartz Composer. I did the QC programming on this; the composition loaded movie clips and applied image effects from a real-time data source over bluetooth.
And while in Vancouver, I did some updates to the QC for the Vancouver International Film Centre with my colleagues at Urban Visuals.
