I have mentioned this before but I'd like to see something on the Dredd universe, possibly from a non-fictional perspective. It was inspired by D'Israeli's inspired look at the different takes on Mega-City One (and digging out that thread might uncover more such suggestions). If he wasn't interested in polishing it up (although he has already done most of the work) I'm sure Tharg could task one of the other article-writing droids to finish it off. It strikes me
this is exactly the kind of thing that should be in the Judge Dredd Megazine.
I'm sure there are a lot of other things that are simmering away at the back of droids minds like this which could be developed (Rufus, for example, is fiercely knowledgeable about British comics art and if you could tap into that you'd have enough material to keep you going for a while). If a theme emerged then some kind of book wouldn't seem outrageous somewhere down the line (perhaps, say, a book looking at the creation and development of Dredd's world from a less - in-universe perspective - it could be fleshed out with interviews and even a kind of "director's commentary" going through the stories discussing what they were thinking planning at each stage).
2. Art Attack!
Get artists to go back over some of their oldest work and take it apart, figuring out how they'd approach it now.
That is a great idea (OK they all are but this one in particular) - I remember enjoying the one page feature in Marvel UK's Daredevils where artists showed off some of their earliest work (and the thread on Dave Gibbons early work made me feel there was an article just in that). Perhaps do a kind of "before they were droids" feature? How they started, what training they had, how they broke into the industry and then finish it off with how they feel their art has evolved since. It'd also be a chance to reprint any art the droids sent to 2000AD - we dug out Lee Carter's drawings that appeared on the letters page and there are others (Buttonman has a list doesn't he?).
