Well I am liking this Prezi business. Have played around with this and had great fun. I will probably give this a go when they let me loose on the Medical Student Inductions. I have already started creating a Prezi for that. It won't be for a while yet, but I think it's best to prepare while I've got a spare min or two. Hopefully I will knock their socks off and they will actually sit up take note of what I am telling them. Powerpoints they've all seen before so it can be a bit boring.
The other 2 data visualisation / slideshare I've not really looked that deep into. I don't think it would benefit me in my line of work. There wouldn't be any use of them for me.
