They really have been in recent years. I can think of at least 2 penguin movies that were released recently (and I have yet to see either of them). This little guy I created for a children's magazine, though he'd work great on a greeting card, too!
BTW, for more new work, be sure to visit my website. I've been hectically busy lately, but new work is still being added, and I haven't mentioned it on here in a while. :-)
