Yet another continuum of rep-3-tiles, i.e., self-similarly trisectable 2D figures. Two others are parallelogram skewings of the sqrt 3 by 1 rectangle (first figure on balanced.htm) and the stretchings of "floppy fudgeflake" in continuum.htm. This time we have a countablegon rather than a frac-tile. The trisection is easy (harder if you don't know it's self-similar) and is left as an exercise.
