Slightly off topic. How big are these currencies that they are carrying around anyway? The way I picture it in my mind is a chip is the size of...well, say a flat potato chip. A broam being a like the size of a super bounce ball. I am sure that is not the case because it would be aufully difficult to carry a decent amount of money around if that were so. I just don't remember seeing an actual size given.
I may have missed it given that I finished the book in only 4 days.
