Buddhist Basics Resources

Know of any great sites for resources on Buddhist basics? I’m especially interested in printable charts, graphs, and the likes similar to those at the bottom of this page (I would have posted them here as I think they’re great and well worth spreading, but the author explicitly asks that content from the site not be used elsewhere).

I’ve just stumbled across a great one that seems to be a hidden gem: http://www.aimwell.org/

There and a host of books, sutta translations, images and chants. Check it out.
