I just learned about ViewAt from the Webware blog. It offers extraordinary panoramic photographs from around the world, and lets you use a special application that shows a 360 degree view.
These images are great for any Geography class, and are especially good opportunities for English Language Learners to describe them verbally and in writing. Some of the photos might even be from their native countries, which makes it doubling appealing.
I’ve placed the link on my Geography page under Sites That Cover Many Areas.
