Yes, today only I came to know about Cooliris Plugin For PowerPoint from channel10, though I have been using its browser plugin since few days.xgamer said:
pptPlex looks good... But it seems limited feature and limited support.
I have been using picLens ( http://www.cooliris.com/ ) for a while for helping our sales team with presentation. The effects are quite good. It supports PP 2003 and Keynote. Has IE/firefox plugins.
I think MS should make pptFlex full featured so that it can become competitive to products like picLens and will help in promoting products like touchwall.
Let us hope pptPlex will further improve.
