I have produced a firstPrezi about Euler Math Toolbox. Click on the image to start the presentation.

It is a first try and should be considered pre-alpha. I had some problems with the English language. Of course, one would like to sound like a professional speaker, which is not so easy if English is not the native language.  Moreover, I am completely new to the Prezi software. In retrospect, I liked very much this style of presentation and found it quite easy to assemble. I recommend you have a look at Prezi. Of course, it is a web based software putting still another private item into the cloud. But for public presentations it seems to be a good idea.

If you are interested, I did the sound editing with Audacity and used a Logitech 9000 Pro camera as mic. The sound levels may be a bit too low.
