Put your presentation into TVnima!
I have chanced upon this interesting application while surfing through the web. TVanima, currently in its alpha stage, is an online 3D application that allows you to create a TV news program by inserting media such as photographs, images, narrations and videos. There will be a news presenter who will do the talk for you. You can then publish you finished work onto the web. If you have a PowerPoint presentation that you want to put on web, try TVanima.
