Mono Monday - Optical Illusion

A sincere thanks to the organisers of the various challenges that come up each week.  I was short of an image today so went looking on the Challenges section of the forums and found that today's mono Monday challenge was 'optical illusions'.  

Not easy and I've got limited opportunity to spend much time on this tonight so I quickly went searching for a pack of cards (for the stock in trade of the magician/illusionist) and a magnifying glass.  I'm hoping the weather may buck up a bit this week.  So far the forecaster suggests dull and rainy all week.  That'll be no sunrises and sunsets then!
