If you have a high speed connection you may want to check out Google Earth. Just go to Google and search for 'Google Earth'. Go to the Google Earth website and download the installation program. Its about 11.5 mb and a full install will use about 2 GB of disk space.
You can travel anywhere in the world. Lots of places have high resolution images. Try turning on the 3D buildings and visit NY. Most of all just explore and be prepared to waste hours of your time.
