If Google Earth knocked your mind out, check out street view.
And while you are at it, why dont you check out Tashkeel http://tashkeel.googlelabs.com/
look at how google will let you write Arabic Chat language and display it in Arabic writing with Tashkeel. Amazing!
By the way, if you just want to use chat language and get it transformed to Arabic, you can use Microsoft Free software called Maren http://www.microsoft.com/middleeast/egypt/cmic/maren/
It will allow you to write 3ammar and while writing it will transform to عمار on the fly (but without tashkeel)
enjoy and keep you eye open to what Google is planning, me think it is going to be the next Microsoft
