Happy pi day! This is a drawing of a sphere made of little cubelets done by my AxiDraw V3A3 pen plotter, using black and grey Pentel Energel 0.7 pens on 18gsm white card stock. Cubelets are included or excluded depending on the bits of the binary expansion of pi.

For Star Wars day, two Tattooine beach sunsets. (Does Tattooine have beaches? I don't care.) Drawn by my #axidraw v3a3 (with brushless z servo upgrade) using Pentel EnerGel pens. #penplotter #maythe4thbewithyou

In the last few weeks I've received a giant pile of pen-plotter postcards as part of #ptpx These ones are from

Here's thumbnails of the 16 plots I sent out for #ptpx04 #penplotter #axidraw

Is #plottertwitter the right Htag to use here for pen plotter related stuff? (This one made using my #axidraw MiniKit 2 from a photo of Gino Robair. The image-to-plot code is still a work in progress.)
