I indulge in a number of fairly geeky projects in my spare time. I'll often write write up how I've done them; here is a small collection of some of the more interesting projects.

Papercraft

During the course of my PhD work I investigated the distortion-free unfolding of model geometry into a 2D net for good quality texturing. I applied some of these techniques to models from early 3D computer games, and made these unfolded nets available for free online. This led to two magazine articles (in Jumpbutton and Computer Gaming World - see left) and a TV appearance (on ABC2's Good Game - see right). Links to the articles can be found here and here; a link to the TV segment can be found here.

Ultrasonics History

In 2003 I had helped kick off an initiative to record and document the development and history of Ultrasound technology in Australia. The materials and equipment collated are now stored and displayed by the Powerhouse museum in Sydney, Australia.

Open-source DICOM writer for IDL

I developed an open-source library for the writing of DICOM images in IDL. It has enjoyed wide use, and part or all of the library has been included in a number of third-party packages (link, link, link, and link).
