I am curious to know if anyone has any knowledge about a phenomena I observed at a local supermarket recently. There was a display stand base, box like in construction probably two foot x two foot square with objects in a tray on top. It is the base that caught my attention. All the sides were covered in small round holes close together no more than a couple of millimetres in diameter. If you stood away from the display stand by a about a couple of metres and looked through the holes at the front of the stand to the holes at the back. The holes at the back of the stand appeared magnified by a large percentage. They were probably one hundred times larger a couple of centimetres in diameter at least. The further you stood away from stand the larger the holes at the rear of the display base appeared. When you walked towards it the holes became smaller at the rear. I have not experienced this type of effect though it does seem similar to railings crossing over each other from a distance. Though this was definitely a magnifying effect which I have not seen before could anyone enlighten,thanks.
