You are trapped in a box, which seems rather unpleasant.

Scan the image with your mouse pointer to find areas that light up. You will find eight star-x-pairs and one letterbox.

First, the letterbox must be completed. Notice that only every third letter of the alphabet is given. Also notice that the middle star shape of the box is the same as the star shape in all star-x-pairs. Finally, notice that the x in each pair is seemingly 1, 2 or 3 steps away from its star. These three things should tell you how to complete the box: Augment it with the rest of the letters of the alphabet by extending it outwards in each direction (J-K-L eastwards, S-T-U southwestwards etc). Doing this you will see that Y and Z are not included, hence the clue below the image “No Y, no Z”.

Finally, overlay each star-x-pair on the completed letter box (the star in the pair on top of the center star of the letter box). Read the letter marked by the x.
