Hi Product Hunt! I've always loved the moment your brain gets fooled, so I built Opticalillusions.com: a growing library of original illusions, each with a short, plain explanation of why it works. It's free, there's a new illusion every week, and teachers are welcome to use the worksheets. Which one fooled you first? I'd love your feedback.
