BBC developed a website to accompany a documentary called 'Walking with Cavemen.' Within this rich set of resources is an area called 'Cavemen Facts.' I like the grid and icon structure of the root menu. When you click on a link or image, a window pops up with more information about the particular species. Within the pop up are additional media resources including audio and video and the ability to look at different images of the species.
Another thing that I really like is that the root page stays open behind the pop up, and the pop up window is small enough to let you know that the original menu is still just one click away. I think I would like to organize my own course project page in a similar way, with a root level menu and then a next level pop up that contains links to more specific resources.
A podcast that I am a currently following is "Appy Hours 4 U," a show dedicated to exploring apps for education. The production quality is slightly low (not the content), and when thinking about something as visual as an iPad it can be a disjointed experience if you don't look at the apps yourself while listening. I do like that this content is being produced by educators purely out of their desire to share information and ideas.
NPR's popular Wait Wait...Don't Tell Me! radio program has a podcast/rss feed available for digital downloads of the broadcasted program each week. While it sits in between entertainment and education, I find that I learn the most about current events, history, and random facts via this podcast more than any other audio-only outlet.
