My main academic task right now is revising my Infinity, Causation and Paradox book manuscript in light of referee comments. One of the tasks a referee set me is including more diagrams (the original only had one). This is a fun break from writing. I'm doing some of the drawings with TikZ right in the LaTeX file, and some I'm drawing with Inkscape.
Here's Smullyan's rod with exponentially decreasing density (to ensure finite total force). It's a rigid rod suspended over an infinite plane, and it can't fall down because then it would hit the plane but on the other hand it's never in contact with the plane. Art it's not.
