This talk was most definitely for fun — an after-hours audience, with beer. The format of Bettakultcha talks is 20 slides for 15 seconds each (they transition automatically), and you can talk about anything you want.
This was my first time using hand-drawn slides; I had fun. Annotations were added afterwards so this made some kind of sense when uploaded :)
And no, I don't get any kind of kickback for mentioning Paper for iPad. I just think it's brilliant.
