The main reason I missed out on the Autobio panel was because of preparing for the Pat Mills interview; the questions were all set up and ready, but I'd had the slightly last minute idea that yes, I would try to bring along some images after all, and so had hastily burned a CD with Misty pdfs in the morning while having breakfast, and got the epidiascope set up by oxfordslacker Alex Williams; not mentioned much in these reviews yet, but that's because he was rushing around being very unslack and organizing a whole bunch of stuff, putting old pizza boxes into recycling bags, etc.

qms commented on the word epidiascope
For plain folk to get the straight dope
A lecture was one way to cope.
The ones they liked best,
So records attest,
Were blessed with an epidiascope.
