This offered to your attention here is a really fantastic S.I.R.D.S. acronymus for" Single Image Random Dot Stereograms ". Never like on these I have found people literally divided in two categories : those who can see SIRDS and those who cannot. But I think that an "artist" cannot allow himself to stay in the second one, because is like to go to movie and refuse to see Alice in 3-D! So the Mad Hatter is ready to give you the right suggestion how to see correctly SIRDS and the fantastic character here portrayed...Listen to him, is absolutely easy... The MadHatter says: 1)Concentrate your attention only on the SIRDS part of the image.Dont' look at me 2) Bring a coin and put with right hand on the tip of your nose. This usaually reduces the space you usually employ in your perception 3) Say with all your force the magical word "WHAT !". The word is not really important but is important the movment of your eyes that this word forces you to do. 4) The difference you got to use is only that when you say WHAT ! you immediately close mouth and eyes. Here instead think automatically to remain some more seconds with eyes wide-opened. No fear if you do so, automatically the 3-D World of Wonderland will open the doors to You... with incredible new possibilities...and depth!
