People have made some pretty bad ass murals out of cork over the years. Have you considered making one yourself?
Not really, no. I wasn't even aware that cork was so popular as a medium. I'll think about it, but it was something that seemed like a cool way to kill an hour or two. You can learn all sorts of things while simulations run in the background. Before that, I was making paper planes and Warhammer scenarios. :P
However, if one 'sekrit project' I have for summer will fail or prove itself to be beyond my ability or amount of free time, then I might default to doing something more ambitious with cork.
