FreeCard is a open-source
replacement of Apple Computer's HyperCard

-only rapid-application development
FreeCard will improve on HyperCard by adding more and even easier scripting languages, integrated color support, support for Macintosh, Linux, and Windows, a MUCH faster interpreter, and whatever else we come up with.
