This isn’t very practical/important, but it is very cool. I was looking for an ASCII version (all text) of a heart that I could use on Valentine’s Day and I came across Photo2Text.com. It is a site that lets you upload a picture, and then it re-draws that picture with ASCII characters. As a test, I uploaded a small version of this sunflower that I use as my desktop wallpaper.
It then created this for me:
It looks great if you ask me. You have an option with the character set to use. The sunflower was made using the maximum character set. As you reduce the number of characters that can be used, the pictures don’t look as good.
