There's a couple of Kassadin remodels floating around. I can't remember if that's the fan-made one or the one of Riot employee submitted in his application to show his skills (a portfolio piece). Either way, they weren't made as part of Riot's production process (although since the guy was employee, they may use it or at least work from it).
