Here’s another Wild Gears video I made last week in the direct sunlight. This one is speeded up 4 times and matched with a reggae beat.
The holes in Wild Gears are usually lined up in rows. This gear has two rows of small holes, and they alternate, so that if you use both rows, you’ll get a pretty dense design. (Spirograph holes, in comparison, are arranged in a spiral pattern, and make an even denser design if you use them all.)
With the holes in a line, you don’t have to line up the gears every time you change holes – if you’re drawing something like this. However, if you’re drawing a sequence of colors, you have to keep in mind that half of the holes are in the other row.
Ring 210 is in the frame of the Full Page Gear Set, and the circular gear 120 came from the Plentiful Gear Set. There are other combinations of gears that will give a 7-pointed star. The Expanded Table of Points is good for finding them – unless you want to do the math.
