On the campus of Abilene Christian University is one of the most amazing communal sculptures ever seen (and I have been all over the world). It is on the east-central side of the campus and is titled Jacob's Dream.
Taken from the story of Jacob's Ladder, angels fight their way up the ladder into heaven. There are stones all around with a waterfall to act as a reflecting pool in front of the sculpture. It is designed for which ever way the sun is shining down to pass through the wings of the angels and cast a shadow on a proverb in one of the stones. It is truly amazing.
