	Alternatively, they could try some totally new avenues of investigation. The body of the Somerton Man is known to be buried in the cemetery on West Terrace, and so if it were exhumed it would provide DNA that could be analysed in order to identify where he was likely to come from, and perhaps compared with that of potential candidates in order to eliminate them (or not).

	The possibilities thrown up by this case are limited only by the imaginativeness of the supervisor, covering as it does such a wide variety of aspects. Even 60 years on, so little is known for sure that any insights could prove to be decisive - what more could a budding engineer want than to solve one of the most fascinating cold cases in Australian history?

	It would be possible for a group in future years to carry on the work that we have done on the 3-D model, finding a way to manipulate it to produce a passable likeness of the Somerton Man as he might have appeared before he died, with hair colour, eye colour and skin colour all included. Perhaps they could develop a device and software that allows them to automatically scan an object and fuse the scans together to create the 3-D model. There is also the option to integrate the re-designed GUI interface into the existing code, or come up with an even more user-friendly design themselves and use that instead. No doubt they could find yet more ciphers that could be tested and incorporated into the CipherGUI - one such that we considered was the Baconian which is trivially discounted but would be a useful addition to the CipherGUI. If they were so inclined, they might want to apply the techniques and programs developed to similar mysterious deaths, such as the previously mentioned Joseph Saul Marshall case in Sydney.

	The majority of these risks were avoided, and the mitigation techniques were successful in avoiding any of them causing major issues within the project. The effect of sickness and lack of communication was not a problem during the course of the project. However there were a number of occasions when the supervisors were unavailable, but the effect of this was minimised through the use of email. By using SVN as an online backup, it allowed for everyone within the group access to the latest version of data and documentation.

	The first aspect of the project focuses on the analysis of the code, through the use of cryptanalysis and mathematical techniques as well as programs designed to provide mass data analysis. The mathematical techniques looked at confirming and expanding on the statistical analysis and cipher cross off from previous years. The mass data analysis expanded on the current Web Crawler, pattern matcher and Cipher GUI to improve the layout and functionality of these applications.

The main results of the project involved a number of areas; review of previous work, Cipher GUI and Web Crawler expansion and 3D reconstruction. The review of previous years projects concluded that the Code was consistent with being the initial letter of English words. Work on previous years’ Cipher GUI and Web Crawler was improved to remove bugs and to create a more user friendly system.
	The addition of creating a 3D reconstruction of the victim’s face allowed for the project to expand into a new aspect and the use of new techniques. Through the use of David Laserscanner software, a laser line and webcam, the bust taken of the victim was scanned and a model was produced. Using the scans and connecting them together ultimately lead to a 3D model which is a good representation of the victim. However due to time constraints the model couldn’t be modified to correct some of the inaccuracies with the bust.

	The main addition that we were tasked to make this year was to provide a means through which a positive identification of the Somerton Man could be made. In order to do this, we needed to create a likeness of the Somerton Man as he would have appeared whilst he was alive. However, the only existing photographs and other identifiers were made after his death, so some modification would be required to make him appear life-like. The best avenue for creating a likeness was a bust made of his head and shoulders after he had been dead for some while and post-autopsy. This meant that, along with being plaster-coloured and over 60 years old, the bust was not a complete likeness, with his neck flattened and his shoulders hunched due to the body having lain on a slab for several months, and a distinct ridge around his forehead where it had been cut off to examine his brain.

	This meant that our task was three-fold: firstly, we needed to find a method of creating a three-dimensional model of the bust that could be displayed on a computer; secondly, we needed to be able to manipulate the model to fix the inaccuracies introduce post-mortem - such as the forehead ridge; and thirdly we needed to be able to then add colour to the model, based on the coroner's description of his skin, hair and eyes. After completing all those tasks, we would end up with a reasonable likeness of how the Somerton Man may have appeared before he died, which could be then circulated to allow a positive identification to be made.
