The presentation began with some impromptu piano renditions by a number of people - one of whom got a big round of applause - and attracted the attention of a passing music teacher. She's played before! After the lecture we were treated to a duet.
The lecture on Creative Commons copyright had some hitches however as the letter B made several appearances with the boring buffering bogey spoiling the otherwise flawless performance :-) (Our internet bandwidth from our service providers has been throttled for some unknown reason - they are still working to fix it.) I should have downloaded the .mov files before hand...
The videos Wanna Work Together? and Get Creative present the Creative Commons concept very clearly.
I also like this explanation: A Tale of Two Fish by yiibu but I didn't try to show it...
