Geelong has just built a 25m high floating Mega Tree. Anyone seen it in the flesh. It would be an awesome sight I reckon. It has 11,000 reflective discs and can be synchronised to music through a downloadable app. Cost $1 million to make, store and maintain over 5 years. http://www.youtube.com/watch?v=gs_or_2QfQU#t=192 Was anyone here involved or does anyone have any details on what was used.
