The Questacon – the National Science and Technology Centre, is located on the southern shore of Lake Burley Griffin in Canberra, Australia. It is a large centre with more than 200 interactive exhibits relating to science and technology. Here are the results of a scan conducted in September 2012. These scans were taken from a 14min walk around the centre. The data was downloaded and processed in less than 30min. The colored curve indicates the path of the sensor, with the color indicating time (blue early in the scan, and red towards the end).
