This is a twitter bot that when you send it two images it will return the second image re-made with the pixels of the first image only.
This bot is deployed on Heroku, tweet at it to see it in action! @ImagePalette
Here is an example!
The usernames have changed since when these screenshots were taken.
Using only the pixels in the first image it will re-create the second image! This is done by pasing the original image onto the second image and re-size accordinly. After that, we will randomly pick two pixels and switch then if doing so will bring us closer to creating the second image!
