GAV Flash and OECD eXplorer (2008)
As a summer job on Linkoping University I started developing a visual analytics toolkit in Flash (ActionScript). The project was a great success and after just a couple of weeks Statistics Sweden (SCB) and the Organisation for Economic Co-operation and Development (OECD) showed their interest in the project.
This has lead to an application being developed using this toolkit for OECD, and in addition to me three others are now (September 2008) working on the project. The application is called OECD eXplorer and is scheduled to be launched as part of the OECD website, oecd.org in the fall of 2008.

Rigid body simulation (2006)
By: Jonas Andersson, Henrik Cederholm, Markus Johnsson and Jonatan Nyberg
In a course in modelling and simulation we created this rigid body simulation. Implemented in C# and with graphics in OpenGL, it performes collision detection and collision response at interactive rates or even real time depending on the complexity of the scene.

Linnaeus (2007)
By: Markus Johnsson, Jonatan Nyberg, Jakob Rogstadius.
Linnaeus is an example of how genetic algorithms can be used to find solutions to complex problems. The application simulates plant evolution in a closed system, where plants reproduce, compete about nutrition and die. Natural selection ensures both that well-adapted species multiply until a state of balance has been reached and that less successful species die out. The plants are constructed using a grass-like structure with separate stalk segments, leaves and a root system. Internally a two-tank system is used in each plant for collecting water, sunlight and nutrition and converting it to energy. These tanks have threshold levels that represent the different growth phases of the plants. 57 different plant genes ensure both visual and behavioural variety.
This project was the winner of the Media Technology Awards 2008 in the Artistic Elements category. It also received a nomination for Technical Achievement.
