Wishing You a Merry Christmas and a Happy New Year!

Christmas Tree Opposite

A Green, Optical Christmas tree this year.

 A great thank you to all of you, students, anonymous followers, random passer-bys, friendly commentators, for helping keep this page going by stopping by and sending friendly comments once in a while! The New Year promises some surprises ahead, which I will not reveal yet…

In the meantime, please enjoy my cheeky, green greetings using “optical inks”. Please follow the instructions carefully and ask a child if you aren’t sure… they will know!

1. Find a Christmas card you have just received, and which has a blank back page. Keep that blank page handy.
2. Look at the picture attached. Focus on the top third of the tree somewhere, and look for about 30 seconds.
3. Now, quickly turn to your blank page. Your Christmas card should appear with all the right colours! And you can re-use the card…
4. With thanks to Eric Carle’s “Hello, Red Fox”
3. Merry Christmas!
