Right now (afaict), the only tag we have for triangular eyewear is kamina shades, whose wiki describes them as "The distinctive sunglasses that Kamina from Tengen Toppa Gurren Lagann wears." All well and good, but this tag gets used for a lot of pictures with sunglasses that, apart from being triangular, really aren't those distinctive sunglasses; many aren't orange like Kamina's, use a different triangular design, or just don't seem to reference him at all. (Examples from the most recent few pages: post #5041389, post #4354314, post #3700719, post #3559212.)
I think we should either:
1. Rename kamina shades to triangle shades (or triangle sunglasses or whatever) and use this as a catchall tag
2. Keep kamina shades as a tag that implies triangle shades, but is used only for posts where the sunglasses actually resemble Kamina's in both color and shape
3. Keep kamina shades with no change, except to redefine the wiki to make clear it's a catchall tag
Thoughts?
