The extensive dynamic capabilities of browsers allow for platforms of infinite extensibility and omni-functional power to be delivered via the internet. This paper considers the advantages of converting web pages into intelligent immersive omni-functional documents. Such standards-compliant documents can be intermingled with web structures to create powerful models for the next generation of internet usability. The paper documents the advantages of converting every webpage into a calculation platform (named CALCI Websheets) that demonstrate more power than the most advanced spreadsheet tools, and the interesting presentation possibilities associated with it. By providing multi-layered calculation elements, this medium provides powerful paradigms in the ability to calculate, to think and to present. Manipulation of complex data types in such spaces is specifically considered.
