Tangential, on the "lo-fi" theme: Looking at old stuff, I like how typewritten documents with charts literally pencilled in have a certain not-quite-perfect, straight-from-the-lab feel to them. By contrast, anything produced using modern methods, be they TeX or Pages.app, looks so damn... <i>finished</i>, for want of a better word (and any imperfections become jarring, rather than charming). What’s a good way of getting that feel, without resorting to downright emulation of low-tech methods (monospaced or even pixel-based fonts, that xkcd graph look for matplotlib, ...)? (Edit: grammar)
