Today's TED Talk is about flags. Watch the TED Talk. The basic rules of flag design include: Keep it simple. Use meaningful symbolism. Use two to three basic colors. Don't use lettering or seals (too hard to read from the ground when the flag is atop a pole). Be distinctive. I live in Alameda, California. Based on these rules, our flag is well designed. San Francisco, on the other hand, was specifically called out as having a bad flag design in the TED Talk. Here's how Autodesk is pitching in to help out. Sign up today. You too can get involved.
