You can use the pinhole planetarium by looking through it (see above image showing what I saw) or by shining a torch through it so that you get star images projected onto a wall (see below image). Note that the square stars in the below image is due to the pinholes acting like a pinhole camera and projecting an image of the LED of the torch I used.
