Final decision on metaphor: Showing the flow of an IF/else statement.

I decided to go with "Showing the flow of an IF/else statement" because I like how it depicts how the flow of a program is like water that flows downwards and the visuals could be very effective, in the way that the water maps out the path that the program works at. The other concepts were interesting but I felt they lacked a strong metaphor and were perhaps a little too ambitious to complete/construct before the due date.
