assignment 2: of abstracts and prototypes

so, following the water cooler idea that i was rather pleased with, i went around school taking pictures of the various types of water coolers we have around. and found two most common.

and here's the degree of abstraction.

i had a lot of difficulty doing a 3D pictogram for the first stage and so i went straight to 2D. i'm just worried that the simplification or abstraction, rather, was too little for each stage! but that was really the best i could do - i hope tutorial would help give me some ideas...
