+The next experiment deals with the idea of discover an image through the movement of the mouse like it was a flashlight

+I was testing how the pixels behave in three dimensions when a pixel is brighter than other and with the mouse movement.

+Playing with fire is a good idea.
+[[File:Test08.png‎ |thumb| left| 400px  | Pixel chasing ]]
+<br> Finally I made a computer vision program in which a small ball fallows the brightest pixels detected through the web camera, so finally I have my analog torch recognized by the program

+===Stage 4 - Finally I made it===
+Combining different ideas of the previous experiment I was able to came up with this program.
+The Idea, is that you have in this case 8 pictures that you could change clicking the mouse but you can't see the pictures because are hidden in the dark, just like if you were in a cavern, so to  see it you need a light source in this case for me works better with a lighter, also because produce fire so I feel like if i was in a modern age past cave. With the fire the program represents this like a torch that you could move around  and start to discover the pictures.
+[[File:Final.png‎ |thumb| left| 400px  | Digital torch with real torch]]
+<br>In the video the light moves like crazy because there is no source of light in front of the web camera so when I light the lighter the camera detects the change of brightness an update the brightness in the pixels values, so for now on if i move the lighter the digital torch is going to move, also the program has a code in this case to make the torch with a green filter, but this could be change also.
+<br> Test of the final program - digital light fallowing real life lighter [https://vimeo.com/161216134  -click here.-]

+===Conclusions===
+- To understand the entire idea, this works better as an installation instead of just the video documentation.
+- It was a challenge but really fun to do.
+- I want to improve the code with videos instead of pictures, but i need to figure it out how to display videos and use computer vision, without processing crashing.
