Having had a closer look at Google's storage limits, and the scanned file sizes, I have concluded that it is reasonable to post this year's visuals in full. We printed these visuals on overhead transparencies and projected them up on the screen that way. (This puts the visuals directly in the hands of the teacher, who does not need to know how to work a computer projection system; anyone can figure out an overhead.) However, it would also be possible to print them on paper or to project them using a computer projection system.
