I have been looking at different programs for hosting/organizing Panoramas. I came across this post and immediately thought of this thread.
It would be very cool (if it hasn't already been done) to create your book illustrations as 360 panos for a digital publication. I think music and voice could also be added.
I was thinking especially of the panel of the little girl asleep in bed to be able to pan around and see the rest of her room.
Cheers
