Okay, here is what I sent to missriss.
Petri dish resin coasters: I wanted them to be a little Powers of Ten-like, like what you might see if you looked in a glass of water up close (dingy water, of course, since there is plankton in it).
Brain/blood cell reversible headband: Hopefully this was more on the cute than the morbid side. This was a bugger to make, since I decided that not only was I going to try printing on fabric for the first time but I was also going to make sure it was at least water resistant.
Billy Nye rings: When missriss said her favorite scientist was Bill Nye, I knew I had to do something from the theme song. Particularly the "Inertia is a property of matter" line.
I also made a bag but didn't have time to photograph it before I sent.
