wikiCalc

Dan Bricklin -- the original spreadsheet inventor who along with his then partner Bob Frankston created VisiCalc for Apple II's way back in the late 1970s -- has unveiled wikiCalc, a web page authoring tool that works like a cross between a wiki and a spreadsheet.

wikiCalc is for creating and maintaining web pages that include data that has more than just unformatted text, such as schedules, lists, or tables. It combines some of the ease of authoring and multi-person edit capability of a wiki with the familiar formatting and data organizing metaphor of a spreadsheet.
