There were a couple of rows my sister and I found when we were at the Chicago Botanic Garden last May. One was this fountain with the water all in a row.
You couldn't actually see this row until you got down eyeball-to-petal: the tulips had been planted in horizontal rows, so there was a group that were shorter than the others. It turned out really cool.
And more "rows" of water - this time arranged into a waterfall.
