The Coolest Internet Thingy Ever

Google Maps now has "fly-by" mode as part of its "get directions".

Step 1: Go to Google Maps
Step 2: Select "Get Directions".
Step 3: (I recommend:) Type in "San Francisco, CA" to "Danville, CA". (Lots of buildings and mountains to fly past.)
Step 4: Click on the "3D" button.
Step 5: (Important:) Click on the "Pause" button at the lower left hand corner of the map so that everything can load properly. You'll be loading a virtual version of every building, highway, and bridge in the Bay Area.
Step 6: Once it is loaded, let it fly. (Additional pauses may be necessary for people with slower internet connections.)
Step 7: Don't zoom around too much while paused (although you can): The program is still a bit buggy and may "kick you out" to a standard grey street map.
