The coffee table book

So we are looking for an idea...

The coffee table book that we can write/ take photos for on our trip around Australia. Then, once we've taken the publishing world by storm, the book will pay for the whole trip!?!

Some of the ideas we've talked about so far:
* a visual book with photos of our feet in a range of different soils/environments/situations (Cam)
* a gourmet camping cook book with stories and photos of where we cooked each meal (Sue)
* a guide to the op-shops of Australia (Shola)
* a quirky look at the roadhouses of Australia (Sue/Shola)

My rather more predictable idea was to do a picture/story book about all the fabulous sustainability projects happening around Australia. Tim's predictable idea is to do a guide to fishing spots around Australia.

Anyone got any other ideas? (For a cut of the enormous profits!?!?!)
