How to decode:
As noted in the comments, each figure has seven sharp corners. Treating a sharp left turn as $1$ and a sharp right turn as $0$, each figure encodes a 7-digit binary number. These numbers are $$1001000,\, 1100001,\, 1010000,\, 1110000,\, 1011001,\, 0110010,\, 0110000,\, 0110001,\, 0110101.$$ If we interpret these numbers as ASCII, we get a sequence of characters:
H, a, P, p, Y, 2, 0, 1, 5.
