Optimum concentration is needed for this one.

There's nothing quite like getting your brain stretched from a riddle or illusion. We've already had the optical illusion that was a picture of Ben Stiller from Zoolander but upon closer inspection, a picture of a girl appeared, with many saying they saw Beyoncé. Hmmmm. Following on from that, we also had our heads teased by this maths equation. The latest thing to make us put our thinking caps on is a picture from Dancewear Central on Facebook. The optical illusion consists of a picture with animated flamingos, covering the entire picture. While the necks, beaks, arms and tails are all jumbled up in the picture, apparently there is a ballerina in the mass conjunction of it all. In a game completely identical to Where's Wally? can you spot the ballerina hidden in behind all those flamingos?         Got it yet?             Given up?           Ok FINE.                                 Our little ballerina is in the left corner of the picture.
