Nice Piece for Costa!
James Dyson's Water Flow Illusion

This fountain, which appeared at the Royal Horticultural Society's recent Chelsea Flower Show, was designed by noted British vacuum sexifier James Dyson. Inspired by Escher's "Waterfall," Dyson's "Wrong Garden" incorporates a clever design to create the illusion that water flows up each of the four ramps before cascading over the end. A detail of how it really works is below. Massive props to Flickr user zeddy1200, whose photograph, shown above, seems to be the only decent hi-res image of the fountain online.
