Thanks Gilles, I think this is very cool what you are doing.
In fact, way back in an earlier thread, there was a little skirmish over
whether you would be entering or not and you announced that you would
not be. It shocked me at first but then my immediate reaction was to
want to respond with a proposal that maybe you could act in some sort of
technical advisory capacity for participants. But the idea never got
past the fanciful stage and I wasn't sure how it would be received. In
retrospect I kinda wish I'd suggested it then.
On a personal note, I did not enter the contest myself for a complex of
reasons, but one huge obstacle for me was the high resolution required
in the specification. I know that had I made the proposal, and had you
accepted, questions about the pitfalls of producing high res images
would have been salient for me. And still are. It seems to me that
that is one of the milestones that separates you and the other
organizers, who have greater experience technically, from many of us who
are less far along. Just wanted to throw that into the mix as you are
putting together your tuts.
