Presentastic is a demo app I created to show off how easy it is to take advantage of ColdFusion's cool capabilities for working with PowerPoint files. The instructions for creating Presentastic are available via this link. Check it out!
2009-11-19 UPDATE: You asked for it, you got it: The actual code file for PresentasticPlus is available via this link. PresentasticPlus is the version of the app that implements the PDF Portfolio creation functionality referenced at the end of the instruction document.
2009-12-01 UPDATE: The one cool new ColdFusion 9 feature for working with PowerPoint files that the original app didn't showcase was converting HTML to PPT--so in order to showcase this feature, I created a new version: PresentasticGold. The code file for PresentasticGold is available via this link.
