Choose small or large record or both. After choosing with sliders, hit Flag to start. Plays tunes while plotting points intersecting records. The small record imitates an old 45 revolutions per minute (rpm) vinyl disk recording. The larger one is like the old 33 1/3 rpm vinyl recordings.
Plots point at record edge. If select both, puts dots at X position of an edge point on a record and the Y point of the other record. This traces a knot ("Lissajous" figure). The smaller record turns 1.35 times faster that of the larger record, because they set those smaller records to 45 revolutions per minute (rpm) and the large ones were set to 33 1/3 rpm (so 45/33.33). This is a bit like Pluto and Neptune. Pluto is like the larger record (slower orbit and larger radius). Neptune is like the smaller, faster record. Used clones so that I could fade over time at different rates for pen, and each planet. Variant of my Neptune-Pluto project.
