Now, this my fellow readers is freaking cool. I came across this while googling the number of different postcodes in NUS. (I don't know how, and this was SO interesting I never really found out).
Well seeing that it was featured on Feature Projects on Google, I figured it'd be interesting and it was.
Basically this uses a few tools to come up with NUS Central Library in 3D, complete with Search!
Yes, that's right, search for a book and it will give you the exact location! :D
Now, all we need is for this to be actually implemented on Google Earth - i.e. when you search for NUS Central Library and zoom in enough, it should give you this!
