Sister Karen teaches piano lessons, but I thought drawing a piano would be boring and cliche for her birthday card, so wanting to have more fun, I was thinking a bit about composer extraordinaire Beethoven and his monumental mane of hair flying manically around his head during a bombastic performance, but I had already done a t-shirt design for her students depicting his distinctive countenance.  Though also a bit of a cliche, my thoughts turned to penguins with their aptly suited tuxedo look.  In my search for reference, I found the Macaroni penguin... a perfect solution for the flamboyant, crazy, Beethoven-esque look I wanted for my enthusiastic conductor!!  An Opus is an artistic/musical composition of grand scale, so what better way to celebrate a life work of 57 amazing years!
