Mahou.org is a website for fans of Japanese anime. It incorporates a dictionary based on Jim Breen's EDICT database, and a kanji dictionary. Jim Breen's page is more useful as a dictionary, however, Mahou.org's kanji dictionary is superb. Entering the kanji, then clicking on the result brings up a page with exhaustive information about that kanji including example sentences and, perhaps best of all for the learner, frame-by-frame instructions of how to write the kanji, i.e. its stroke order (not all kanji, but most).
