It is possible to find a set of five d orbitals that all have the same shape. They point to the corners of a pentagonal bipyramid. They are linear combinations of the conventional d orbitals. For example, one of them is and it looks like:

Here the x axis is toward and to the left, the y axis is toward and to the right and the z axis is pointing up. Red is positive and cyan is negative. Plotting all five together gives (left: same view as above; right: looking down the z axis):
