It includes articles, history, information, biography challenges and obstacles as well as achievements–called “Einstein the Nobody” before his discovery in 1905).

Also has a section with several physicists speaking of Einstein, E = mc2 etc. Visuals, of course, in all sections and audio in some. Relativity and the Cosmos portion includes clever and short animations. Einstein’s timeline may also be of interest–he was homeschooled and self educated part of his childhood. Also profound Einstein quotes are on the site and an interactive quiz with answer/explanations (Power of Tiny Things). It does have “teacher’s guide” with activities included.
