I had a nice surprise recently when this cover I made for Jacob T. Robinson's lab at Rice University came out. I didn't even know it had been chosen. It’s about immobilizing hydra (not the Marvel comics one) in a microfluidic device so its neurons can be poked and prodded. These little creatures are so cool. They stick to something at one end and then wave their little tentacles around, like a microscopic wacky wavy inflatable tube man. Or even better, like Dee from It's Always Sunny when she learns some new dance moves from one.
