Here’s a very fun animated tessellation picturing birds and cats. Animation truly brings a new dimension to these kind of pictures that use repetition of shapes with no overlaps and no gaps – it additionally helps you see both variations of the image, no matter whether you originally recognised the empty space containing cat shapes, white space containing birds, or both!
Looking forward to hear what you think of this? I never saw tessellations coming to life before. Perhaps once, when I think about it. Think something similar was featured in the “Escher’s working space” video we featured few months ago. Have to check it again just to make sure…
