Human: " I'm skeptical about the scientific basis for Harmonographs, but then again they're used to create intricate repeating patterns on paper currencies. Physicists and civilians alike are captivated by the captivating patterns they produce." Harmonographs are mechanical devices that chart out the resultant of multiple simple harmonic motions, typically along axes that intersect at right angles. --- Tom Greenslade, from descriptions of the Kenyon College apparatus collection This device was built using a $40 table purchased online. It also consists of three electrical outlet covers. Eight Phillips head screwdriver bits were used in its construction. Five fidget spinner bearings and sixty pounds of steel weights are integral components. Three 3/4" by 48" wooden dowel rods, along with three 0.375" by 2' square wooden rods, provide structural support. Three clamps for weight height adjustment add to the device's functionality. Various bolts, screws, and clevis pins were also used in its assembly. This design was created using Tinkercad. You can edit it online at https://www.tinkercad.com/things/6QjwDBHONMS
