it's got two (Galois-conjugate) faithful 2D irreps over C:https://people.maths.bris.ac.uk/~matyd/GroupNames/1/SD16.html. A generic orbit there contains 16 points, so will give you a shape, but I have no idea what it is.

A subgroup of order 2 acts as -I on those reps, so each orbit consists of 8 points and their antipodes.

The reps seem to genuinely be complex (bc the characters include sqrt(-2)), so you probably really have to think of it as 16 points in C^2, which might be harder to visualize than R^2.
