The good folks at ART Evolved have organized a fundraiser for breast cancer research. It runs from now until the end of October.
One way to help out is to submit your own artistic version of a pink dinosaur (I bet they wouldn't turn away pterosaurs, mosasaurs, or thecodonts, either). For every one they recieve, ART Evolved's administrators will donate a dollar to the Canadian Cancer Society.
If you're shy about sharing your drawing skills with the world, don't worry. You can support the cause by donating directly at ART Evolved's Pink Dinosaur Event Page. They have set a goal of $500, but I bet we can top that.
