Thanks for the hunt @astonishedface! I threw this together yesterday just because I wanted a way to browse the various stickers on Twitter, which I couldn't figure out how to do given the current user experience. #StickerSearch is super rough at this point but if people find it useful, I'll throw some polish on there.
This is a classic case of "scratching the itch". I hope Twitter releases a high-polish version of this functionality (along with API integration) but http://euph.io will do in the meantime.
