mission idea "Vector Labyrinth"

I like labyrinth missions.

I would like to add one.

You are given your own coordinate and direction. You should draw a view with some (0-5) quadrangles.

I would like to get a feedback about a mission

specification

vector_labyrinth(your_x, your_y, your_dir) == [quadrangle_1, quadrangle_2..]
quadrangle == [[x1, y1], [x2, y2], [x3, y3], [x4, y4]]
