Open Source Wiki-Spreadsheet

The wikiCalc program lets you make web pages with more than just paragraphs of prose. It combines the ease of authoring and multi-person editing of a wiki with the familiar visual formatting and calculating metaphor of a spreadsheet. Written in Perl and released under the GPL 2.0 license, it can easily be setup to run on almost any server as a web application or on a personal computer to publish by FTP.
