Google Maps.

<p>MIT campus is in an excellent resolution on sattelite photos at Google maps.
You can see cars on the bridge, ships on the river and every separate building. The photo has several years [there is no simmons hall - only work field], but still is very informational.</p>

<p>One can compare MIT campus to other ones ;)...</p>
