Thumbstacks.com – Live Presentations on the Web (link removed). ‘Thumbstacks.com is a new site for making and sharing presentations on the web. This site is just getting started, so if something’s missing, or you can’t find what you need, please let us know. With Thumbstacks.com, you can make presentations – like slideshows, or outlines – right in your web browser. When you’re done, you can share your presentations with anyone, anywhere, just by sending them a link.
It all runs right here, in your web browser. You can create your presentation, save it, modify it, update it, whatever – then click “publish” and you’ll get a link you can use to share it with everyone.’
