While it’s not nearly as impressive as his awesome tour of the 1977 Tenerife Airport disaster, Peter Olsen has sent us another pretty neat file for Google Earth.
This time it’s a model of the “Bankstown Optical Illusion”. This is a two-sided building with a partial roof that was constructed near Bankstown Airport in Sydney. As you pass the building, the illusion makes it appear to be rotating in the wrong direction! You can read about the building in the Google 3D Warehouse, or download the KML to fly there yourself. If you fly there, here is how to make the illusion happen (in Peter’s words):
Do not zoom in. Simply attempt to rotate the model anticlockwise (click and hold the mouse wheel and drag the mouse right). Or pan to the right (click and hold the mouse wheel and shift key and drag mouse right). Notice that the model seems to rotate the wrong way.
Notice also when attempting to rotate the model anticlockwise that the end wall will suddenly seem to becomes transparent.
If you’d rather just see the illusion, I’ve created this short video. It shows the illusion, then zooms closer on the building so you can see how it was actually constructed:
The Google Earth imagery in the area isn’t fresh enough to show the building, but you can view it on NearMap to see what it looks like from above.
As always, nice work Peter!
