Oracle Media Objects, formerly Oracle Card, was a multi-media software development tool for developing multi-media applications, with similar functionality and appearance to Apple Computer' HyperCard. In the early days of HyperCard at least two alternative tools were created outside of Apple, Spinnaker's Plus and SuperCard. Plus was very much like HyperCard, with the notable distinction of being cross-platform, operating on both the Macintosh OS and Windows. SuperCard was Mac-only at the time, and is still a shipping product.
