When I saw the default font (Gill Sans) for the slide type I chose (White), it looked perfect for te type of design. I chose a puzzle-piece sort of design because it expresses ideas clearly, and looks smooth. Its coloration provides a bit of contrast between words, making it even clearer. It’s in a square about ⅔ the height and width of the overall slide. This technically doesn’t conform to the rule of thirds, more like the rule of sixths, as it leaves about a sixth on each side. It’s not quite exact, though. I didn’t use pure black, because it would be too strong.
In reflection, I think I did my slide well. It had an overall "Wow!" reaction among fellow classmates. In addition, it fits everything the assignment needed.
