Application presented at UN Climate Change conference in 2009.. The application calculates the amount of CO2 that will be emitted into the atmosphere till the year 2050. The default scenario can be changed by placing physical cards on the table which are seen by a TUIO Object Tracker. As more cards are placed and activated less CO2 is emitted by 2050 and the black clouds that cover the backgrounds dim.
This application is also a part of the multitouch application suite.
A demo version of this application can be viewed online here.
