There's likely to be some changes in this design before the end, because I haven't quite satisfied one of the three fiendish constraints that I chose from the five that Tom Hart gave us. These two I think I've addressed:
The one I'm not so sure about is this one:
3) Say no to the grid: No two panels can be on the same x- or y-axis. Each border of each panel must exist in its own unique relation to the edges of the page. Circular panels cannot have the same center on any axis. Trapezoids cannot share a continued line.
It's not altogether clear to me if the constraint about "unique relation[s] to the edges of the page" means that no panel borders can be parallel anywhere on the page or if it simply means that multiple squares and rectangles, while permissible, mustn't line up neatly at their edges. If all I have to do is skew the join of regular parallelograms, this won't be so bad. But if every line has to be pitched to its own angle (or curved to its own shape), that'll be a bit tricky.
At any rate, I'm also unsure about the spirit of the constraint, since it's clear that the nine-panel grid lurks behind my current (very sketchy) thumbnails above. But I needed to work out the basic story elements first. I think I can adjust panels for this third constraint if I've misunderstood it.
So, comments welcome, on any aspect of the thumbnails that need 'em!
