Shrinking Pentagons

This star shape is constructed primarily with blue pentagons that are only touching at one point with another blue pentagon. The blue pentagons are shrinking by a half each step to the away from the centre. The purple wedges fill in the gaps between the blue pentagons. The wedges are constructed in the same way--pentagons that shrink by a half. I'm still playing around to make a better looking pattern with pentagons of different scales...
