Optical illusions are older than you think. The first optical illusions date back to 20,000 BC and were seen in caves. Nowadays they are found all over the place – on screens, in books and even in real life. They're a perfect expression of how creatively our brains work when responding to light, colour, shape and movement – and are great inspiration for art and design that leaves a lasting impression.
Here, I've rounded up our favourite and most popular optical illusions. Some went viral on TikTok, and some are classics that have been around for years. If these inspire you, you can create your own illusion art on an iPad for Procreate or graphic design laptop, and share them on your social media platform of choice.
