A Utah Teapot is an ideal design for a geeky ornament. For this one, I generated a vector stipple drawing from a photograph of the source object for this digital design icon. There are certainly many other ways to create a Utah Teapot ornament, including, of course, 3D printing.
In this case, I took our photo of our teapot, adjusted it to give it slightly higher contrast, and loaded it into StippleGen 2.
I removed any background stipples and plotted it on an ornament. The ornament is 2.6 inches in diameter and I used a 0.2 tip Copic Multiliner SP. I have posted the design on thingiverse.
