You’re welcome to download and use for private purposes any of the imagery on the site, except for a very few pictures where I indicate that third party copyright might apply. But if you’d like a giant, 35 x 23 inch poster, full of illusions, you can buy it (along with loads of illusions on bags, T-shirts etc.) from www.Cafepress.co.uk/optoct. I was delighted when I saw the quality of the poster. Each of the illusions is identified with a discreet caption line, so that you’d be able to follow them up on this or other sites.  And of course, lots of these illusions are brand new versions, often with an extra twist of some kind.

Illusions make brilliant gifts.

You’ll also find a poster of the whole of my optical illusion cartoon story.  If you’d like to preview that, read on.

Once again, the poster is available from www.Cafepress.co.uk/optoct, and it’s the cartoon story you can see on the www at www.opticaloctopus.com, which I did about four years ago. I wanted to try to devise a storyline that might work as an animated film, and show how optical transformations might carry a story. Not sure I came up with the greatest ever storyline, but I’d still love to see an animation that really depended on illusions.  With all the new 3D movies – like Up and Christmas Carol – I feel there are brilliant 3D motion effects. But none of them manage to make the difference between a 3D and a 2D world part of the story.
