Ian Griffiths illustrates the core concepts in Avalon animation by implementing a custom font size animation class. Basically, "animation" in Avalon means "changing an object's value over a range in a given time," e.g. changing a font size from 10 to 72 in 4 seconds or an X coordinate from 10 to 100 in 2 seconds. Animation seemed so fancy to me until I broke it down in my head in this way.
