Urban Sculpture in Honolulu

I like sculptures; and we have a lot of them on the island that we can slow down and enjoy them.  Styles range from the more traditional life like statue such as the Kamehameha and St. Mark statue, to the more whimsical concrete people in tube sliding down a grassy hill, to the bronze replica of wood stick and coconut leaves horse sculpture.  The stacking sculpture is feature in Ala Moana commercial back in the 80’s.  If anyone see the water feature sculpture, please help with an upload.
