Dragon Illusion

This is a cool optical illusion. I've downloaded and made one as per the given instructions and got stunned. When I moved left and right, this dragon stares at me and seem like moving its head. Have a look at the video, to see what I mean.

How does it work? If we move around when viewing a solid object, our brain knows how the object we are looking at should behave. However the dragon gives us the wrong clues, because we mis-interpret what its shape is. We assume that the nose of the dragon is pointing out towards us, but in fact the dragon's head is concave.

Download a copy of the actual dragon and try this illusion for yourself. you have printed the dragon out (a colour printer is best since this is a colour image) then you can cut out the dragon, fold and stick it, and you will be able to see this fantastic illusion yourself. When you print the page out, you will see that the instructions for folding the dragon are included. Please follow these instructions exactly.

Why you shouldn't post your picture on the internet

Ever wonder whether those funny photos you get in your e-mail and see on web sites are real? Some are, but with the advent of easy-to-use photo touch-up software, more and more people are manipulating and combining one or more innocent images to make a brand new bizarre image. Here is the original photo of a boy standing with several other boys and 33 crazy, funny manipulations of the boy and his rather distinctive face.

Color Keying technique (Also called as chroma key)

How often did you get stunned with your favourite hero flying or floating in the sky? Ever thought of how harrypotter fly high with his broomstick? All this is nothing but the outcome of the color keying technique!

Color keying is a method of removing a particular colour from a video. Suppose you are wearing a dress completely red in color covering full body except your head. If i take a video of your complete body and key off the red colour, what i get in the screen is the MAGICAL you! Your head floating without your body! Did you get what does color keying mean? Green and blue are the most commonly used color for keying off.

Now, how does this technique make someone float in the sky? Take a video of the sky where you want someone to float. Take another video of somebody making actions in a room with a unique color as his background screen. Now open up a video editing software ( I usually use Adobe after effects to do this). Key off the color in that background screen and layer this video to the sky video ( If you do not understand about the layering and video editing stuff, its OK! Just get the idea as of now. This layering is a simple process called as compositing.) You will see the guy making those actions in the sky. Color keying is as simple as that!
