I love Ocarina of Time. Loves it.
I decided to draw up the c-buttons in Inkscape and laser cut them. I tried making them bigger, I tried cutting out the triangle instead of etching it, too. Nothing looked quite as nice as the smaller c-buttons with etched triangles.
I have so many things I want to make with them. Right now, though, I am limited to making them look pretty in photos. I'll need a little more time, some clamps and a drill to get things really going. The original idea was to make song necklaces. Like a necklace of Epona's Song, and a necklace of Zelda's Lullaby.
I think they'd made excellent earrings as well!
I've included the file I used to cut them out if you'd like to make your own. And you definitely should.
