HotSauce (code-named Project X) was experimental software developed by Apple Computer as a sample application of its Meta Content Framework. HotSauce generated a 3D visualization of the contents of an MCF file, for example, a website sitemap. It could also be used to navigate the contents of the user's hard drive.
HotSauce was never released in a final version and while MCF was adopted by thousands of websites, including Yahoo!, most users saw no point in navigating them in a 3D space. The project was discontinued along with MCF shortly after Steve Jobs' return to the company in 1997.
