By the way, none of these artists have any idea that I picked their products out of the ether to share with you. We are not in cahoots, nor do I get any cut of any sales, although I wouldn't be sad if a modest royalty check made it my way... ha! But just so we're clear, this here is an honest-to-goodness advertising-free list of sciart awesomeness. Yup!
