Uh... I'm not sure it's a fixation, but I'm
particular to cels of people with musical
instruments, cels of clowns/mimes, cels with
graves, and cels with origami... and probably a
ton of other stuff I don't realize.  Sadly I don't
have more than a handful of any of them I think. 
I tend to try to stick with the stuff I've seen
the anime though, so perhaps I'm not "fixated
enough?" ^_~

Keys
Can't help drooling at a good violin regardless...
