ON NOW Matters of science have long struck an artistic chord. A great example: the way that specimens under a microscope can look like colourful, hyper-detailed paintings. The Ontario Science Centre stimulates your synapses with its Spark! The Heart of Art and Science exhibition, which examines the unseen beauty of cells and molecular processes—from mice embryos to cancer cells—through artistically rendered images and 3D animated videos. Visitors can also create their own visuals as part of the DIY Body Project, an interactive textile installation where rearranged body parts generate anatomical masterpieces.
