131
STRIPES
131

132
MARK.13
132
MARK.16
134
explore
135
SPIDERWEB
140 STAREDGE

using double the angle create a kink unless tangle=0
140
STARGON

0.5 notch gives a star 0 generates no kink
141 STARGON penta

full kink using minus to plus values
142
STARGON starfish

>1 notch inverts the kink 1 notch adds staight lines
143 STARGON 3

repetitions create surpricing shapes
147
FRACTALONS

fractal using recursion
151
NEPHROID

127 TIPGON version
152 STAR.NEPHROID

2-poly (line) used for TIP.STARGON
152 STAR.NEPHROID

KINK 0.95 makes STARGON very pointy
152 STAR.NEPHROID

0.95 kink but even N makes it symmetrical
152 STAR.NEPRHOID
152 TIP. STARGON

in this case shown without the “rott” rotation
