This is probably old news to many of you but I just realised that Street View in 3D is still available on Google Maps.
On April 1st this year Google turned Street View into 3D. The Street Views however soon returned to normal and that, I thought, was that. However I discovered today that if you right click on Street View there is an option to turn '3D mode' on.
So if you have a pair of 3D glasses lying around you can now see the world in glorious 3D (it's almost as good as looking out the window).
