Alan Jacob won the 1st prize at the Gallery of Rheology (2018 SOR) with this image below:

Eye of Sauron: Gallium is a liquid metal that form a highly elastic native oxide skin. The oxide skin surrounds the liquid metal leading to creases on the air liquid metal interface. A high energy Concentric Backscattering Detector (CBS) is used to obtain an electron microscopy image which captures a highly contrast image of the wrinkles present on the air-liquid metal interface. The crinkles resemble flames when false colored is applied. This image indicates the rich interfacial phenomenon of liquid metals which is yet to be properly understood.
