An acoustic day in the life of the Australian bush as revealed in a series of zoomable false-color spectrograms. The transition from layer 8 (0.2s/px) to layer 9 (0.1s/px) is the transition from false-color BGN-POW-CVR spectrograms to the pseudo-color cubehelix representation.

A note to the reviewers: The host for the tiles changed their public API on the 24th of July 2015. This resulted in the demo being broken for two days until the 26th of July 2015 when it was updated and repaired. Additionally it seems our host is suffering from intermittent performance problems - if the tiles are loading slowly please try again later.
