I love being able to vent discworld plot ideas on this forum
I had a few more inspiration particles collide with my head yesterday.
A discworld book about enviromentalism/pollution/global warming and teh Gaia principle would be interesting. It feels to me like a Granny Weatherwax sort of book but the river Ankh must be a main character in this some how. So many avenues to explore I feel.
Another idea that would be interesting is having comic books/ super hero(es) in Discworld. Especially since they might end up being quite un spectacular in all that magic and Carrot etc. A magically enhanced spider biting a little street urchin?

It kinda feels like a little like a watch story line.
Here's hoping (fingers crossed)
