Here is another of the many detail images available when photographing the Musket Organ at Springfield Armory National Historic Site. Another classic repeating pattern composition taken by looking along the length of one side of the display.
Besides the larger pattern of the muskets, there are many detailed repeating patterns: barrels, stocks, hammers, sites, and clamps. Much like photographing railroad tracks, you see these repeating details converge upon each other as they fade into the distance along the left edge of the image.
