I was searching travel information of Taiwan for my parents and saw this image “Smiling Taiwan, Feel it! Love it!” by chance. I like it very much and thought it would be cool if I make one similar for my parents.
I started to try a few tools. Mosamic is good enough for my purpose. It is a free mosaic software which can be used to create mosaics of any image. It’s easy to use and I made my own image in a few minutes.
