Can you work out what is going on?<\/p>\n<p class=\"dcr-130mj7b\">The illusion is the latest masterpiece from Olivier Redon, a French-American inventor, who has had his creations used in museums and on TV programmes around the world.<\/p>\n<p class=\"dcr-130mj7b\">For today\u2019s puzzles, I present five of Redon\u2019s most brilliant images. The challenge is to figure out how he managed to create them.<\/p>\n<p class=\"dcr-130mj7b\"><strong>1. Ceci n\u2019est pas une canette<\/strong><\/p>\n<p class=\"dcr-130mj7b\"><em>Another look at the can. What are you actually looking at?<\/em><\/p>\n<p class=\"dcr-130mj7b\"><strong>2. The Oh La La Box<\/strong><\/p>\n<p class=\"dcr-130mj7b\"><em>This is not a red box! What is Redon actually holding in his hand?<\/em><\/p>\n<p class=\"dcr-130mj7b\"><strong>3. Twin dinos<\/strong><\/p>\n<p class=\"dcr-130mj7b\"><em>This iPhone image is of two dinosaurs that are the same size. How did Redon take the image?<\/em><\/p>\n<p class=\"dcr-130mj7b\"><strong>4. Fragile<\/strong><\/p>\n<p class=\"dcr-130mj7b\"><em>This is a portrait of Redon and his daughter. How was it taken?<\/em><\/p>\n<p class=\"dcr-130mj7b\"><strong>5. The transparent cube<\/strong><\/p>\n<p class=\"dcr-130mj7b\"><em>This looks like cube with words on three external sides. But can you see what you are really looking at?<\/em><\/p>\n<p class=\"dcr-130mj7b\">I\u2019ll be back at 5pm UK with the reveals for each of these images. Please do return. The illusions are sensational.<\/p>\n<p class=\"dcr-130mj7b\">UPDATE: You can see the reveals here.<\/p>\n<p class=\"dcr-130mj7b\">PLEASE NO SPOILERS.<\/p>\n<p class=\"dcr-130mj7b\">Instead, please discuss your favourite optical illusions.<\/p>\n<p class=\"dcr-130mj7b\"><em>All photographs are copyright Oliver Redon.
