Here is my proposal for your contest. I created two rooftops symbolizing an "F" (referring to the name Flint) The icon works well along with the name or as a stand alone graphic, one that will be easy remembered.
I look forward to your comments or thoughts. It would be my pleasure to work up any variations.
#84 is interesting, I like how the house cutout makes the whole thing a directional arrow. However, we don't build houses so is misleading - can you put an actual arrowhead shape inside the triangle and see what happens. Keep experimenting!
