Something a client wanted but ending up not using. Maybe someday I will convert it to AS3 and create a version where you pull variables from XML data to generate a dynamic gauge that might actually be useful for people. For now, however, it remains a toy.
Some interesting or not obvious things about the gauge:
1. Calculating where the needle should point accurately is not as easy as one might initially think. I thank Pythagoras.
2. Each colored tick is its own individual shape with a flat color, which also had to be calculated. It is not a masked overlay, in other words. On a related note, I can count in hex. 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0A, 0B, 0C, 0D, 0F, 10… imagine that if we all had 15 fingers this might be normal. I thank my favorite teacher ever, Mr. Walters, for introducing me to that last thought.
