CommanderD has been scouring the internet looking for Krystal sprites to turn into bead art in real life. He uses one colored bead per pixel on a special pegboard. After that, he heats them to melt them slightly together. After they have time to cool and flatten, they become what you see in these photos. CommanderD has some of these for sale, and can make more on commission if you have another sprite you want done.
In the past, two of CommanderD's Star Fox works were even featured in Nintendo's Miiverse Christmas Tree post.
Check out CommanderD's bead art blog, where he posts updates and photos of his work. There are a lot more Star Fox related bead arts to be found there in addition to Krystal.
