This unique washbasin by HighTech Design was inspired by the spiral shape of ammonite shell. In case you didn't know, Ammonites are an extinct species of free-swimming molluscs who lived in the ancient oceans around the same time that the dinosaurs walked the Earth and disappeared during the same extinction event[1]. Our panda fans from Facebook loved it, but Andre and Darik pointed out that it must be "a pain in the ass to clean".
