Triangle Set

A simple set of Triangles juxtapositioned next to one another with a reduction in size. The code that generates this figure is shown below:

startshape B

rule A{
TRIANGLE{b 0.2}
TRIANGLE{s 0.95 b 1}
A{s 0.9}
}

rule B{
A{}
A{x 0.5 y 0.3 flip 180}
A{x 1}
A{x 0.5 y 0.88}
}

Now adding a few color elements to the code gets us this.
