280slides Online “Keynote” app

I just saw the http://280slides.com/ site and thought it was pretty cool. It’s an online presentation maker that has been crafted to function and feel like Apple’s Keynote application. It works pretty well. I only had a few small things not work for me in Safari on Mac (Ben, start using Safari on the PC already! :) )

I was really blown away when, after posting the question on their support site, I found out that this app is NOT built in Flex or Silverlight or anything like that, but that it’s all JAVASCRIPT!! That’s right javascript! It seems that it wa sbuilt using a Javascript UI framework called Objective-J. There is a little more detail about that in Alex Le’s blog entry.

Also, if you want to compare this to an impressive Flex based presentation editor, check out SlideRocket.
