Google Street View 3D
Funny, but not sure if it’s an April Fools joke. 
Just looking at some Street View imagery, when I noticed a little orange guy with 3D glasses right underneath the controls, as can be seen to the right. Turns out that when you click it, it will show you the imagery in — yeah, you guessed that right 
— 3D. You do need a pair of those red/green 3D glasses though. Which of course, I don’t have. That figures… 
So, unfortunately I can’t try it out right now, but if you do happen to have some 3D glasses laying around, you could, for instance, have a look at the entrance of the Efteling, which is a theme park a few kilometers from here. I have no idea how extensive this 3D coverage is, but it might just be available everywhere, just some feature Google’s camera cars have had since the beginning but they just haven’t told us about. Anyway, I didn’t do an extensive search, but I have yet to discover a Street View area that hasn’t got 3D imagery.
Next up on my todo list: fashion some 3D glasses somehow, or just get a pair somewhere. 
Update (April 9th, 2010)
Apparently, it was just an April Fools joke after all. The option is now gone.
