Tom Batiuk’s comic strip Funky Winkerbean expresses the situation well. In a sequence of strips from September 2001, we learn that Linda Lopez has spent a part of her summer preparing all of her overhead transparencies for the school year. In the fall she discovers that the school has converted to computer-equipped classrooms and discarded the overhead projectors. Her transparencies are suddenly useless! To solve her dilemma, she tries to smuggle her own overhead projector into school, but, alas, her bulky raincoat alerts administrators. Finally, she resorts to a darkened classroom, a flashlight, and hand-held overhead transparencies.
