The initial intent of this design was to put the "valley of the shadow of death" David speaks of below into a visualization.
What we didn't know at the time we were developing the design was that the "valley" was indeed literal - it actual exists!
The Kidron Valley (Valley of the Shadow of Death) is located outside Jerusalem’s eastern wall and is full of both ancient and modern burial sites. Its location puts it in shadow for most of the day. This valley links up to the south with the Hinnom Valley where infants were often sacrificed to Moloch.
Jesus actually walked through this valley after being arrested at the garden of Gethsemane.
Check out the below video of a couple who frequently explore Israel in search of the locations found in the Bible. They go into detail about the above-mentioned valleys.
Psalms 23 - A Psalm of David.
1 The LORD is my shepherd; I shall not want. 2 He maketh me to lie down in green pastures: he leadeth me beside the still waters. 3 He restoreth my soul: he leadeth me in the paths of righteousness for his name's sake. 4 Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me. 5 Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over. 6 Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the LORD for ever.
