Houdini writes – “…Knowing nothing about how to do tiles mosaic and where to by the stuff, I started to do some searchs on google image to find an appropriate drawing to convert into mosaic. With a bit of luck I knew I could find one that will exactly fit my wills : not too small, and not to large. A 25×25 tiles mosaic was my absolute limit as it’s already involving 625 tiles. I finally failed in google images, and before starting to convert a bigger image into a smaller one, I did some extra effort to find an original sprite with the size I wanted (pixel design is so well done that I couldn’t expect to get the same quality by myself). I finally found the exact 18×18 pixels image I wanted, in a backup of a nintendo GameBoy Advance cartrige. I had to extract the content and one particular design on a splash screen fitted my needs perfectly.” – Link.
