Take a dictionary, add AJAX-y goodness, season to taste and you've got ObjectGraph, a dictionary that displays results automagically with each keystroke. The interface works like Google Suggest, where a dropdown DIV element displays results as you type. You have your choice of four different word sets: Classical is the websters 1913 dictionary (which is rather amusingly out of date), the freely available FOLDOC online dictionary (which should probably really be the default selection), the periodic elements, and a Thesaurus mode.
