Do...these optical illusions and boggle your brain. The front of each two-sided card is a drawing of an optical illusion. The back of each card describes the illusion and explains what's going on to create it. One card gives an overview of optical illusions and how they play tricks on your brain or eyes. The fifteen cards come in a clear, plastic case that snaps tight.
