Well I really dislike seeing #respondsTo: et al in general code so I'd propose something along the lines of a list of known cursors (it's reasonable in my opinion to make that list using reflection at either startup or add-new-cursor time) and then 

Cursor class >> #named: aSymbol
   ^  cursorList at: aSymbol ifAbsent:[self normal]
