I might have read Manga too much
, but I still am wondering whether something like Captain tsubasa or Prince of Tennis are reasonable? Even though it looks like very "imaginative", but the creator put quite a bit of logical reason behind it. Say, for example Drive B in Prince of tennis happens when we put a lot of spin behind our shot, it will jump to create B shape ( If I'm not wrong ). In this case, it would probably be interesting if one people can put logical analysis behind one techinique from specific anime / manga 
Sport special effect
Logically, it looks like can be done.. but technically I think it's very hard
