The tag line for Prezi (http://prezi.com/) is “Create astonishing presentations live and on the web” and they go on to assure the reader that anyone can do it.
It is easy to sign up for a free account, and there is a really good free educational offer. having played around for about 90 minutes I have created a presentation about me – well at least the me at the University of Reading. With more time I could have added pictures and some clever effects.
I don’t think it will take over from PowerPoint, but I think as something different it is fantastic.

The embedded Prezi in the above is not showing on the computer I am currently using: Windows 7 and IE.
Is it over enthiusiastic blocking?
Seems to be a problem in IE + Windows 7 as I can’t view it either. Works fine in Firefox + Windows 7 though…
