On today’s episode of Bre Petis’ I Make Things, my pal Nick Farr of HacDC demonstrates the Polyalphabetic Substitution Cypher Slide Rule (PASCSR) he made and uploaded to Thingiverse. Thingiverse launches today, too. It’s a site, created by Bre and Zach Hoeken, where you can share your digital designs/object files with the world. Cool.
