Thumbstacks, Online Presentation Tool

Thumbstacks is an online replacement for PowerPoint or any other presentation tools. It allows users to build online presentations and share them by sending them a link. Users who are hooked to PPT's flashy transitions and animations might balk at this red headed step child but for an online choice that works wherever you are....not too bad. I would like to see them add the ability to upload PPT files. Perhaps after Google acquires them...Who needs Micro$oft Office? With all the online tools available, one could save a lot of money by using these handy tools.
