Only just catching up on my blog reading from the last week or so this evening - so only just came across this, but  its pretty cool! - it's like deep zoom for power point - the
project is  pptPlex from the OfficeLabs team.

I wonder if anyone at teched / codecamp in New Zealand this year will be using it... I normally do a mind map when I'm structuring a presentation, proposal for a client/whatever - be great to actually present the mind map itself then zoom in to show the details...mmm
