You may notice from the image above (and the video below) that Greg&#8217;s design is not actually laser cut&#8230; it has been 3D printed.

This can be calculated for any round-ish shape using mathematical magic, but if equations make you wobbly, then you can cheat a little and use the approximated ratio of:<\/p>\n<p style=\"padding-left: 60px\"><em>Slot Length = Disk Radius * 0.293<\/em><\/p>\n<p>Wobblers can come in a number of forms, and with the repeated motion of the disks as they roll along, there is a great opportunity to laser etch onto the surfaces for further visual impact. It is also possible to apply the same mathematics to other Wobbler constructions; perhaps the most notable example of this is John Edmark&#8217;s laser cut Rollipses.<\/p>\n<p>Click through for a video of yet another stunning kinetic mathematical wonder from John Edmark, as well as a collection of Wobblers presented by Tim at Grand Illusions.   <!--more--><\/p>\n<p><iframe loading=\"lazy\" title=\"Rollipses\" src=\"https:\/\/player.vimeo.com\/video\/20824153?dnt=1&amp;app_id=122963\" width=\"640\" height=\"480\" frameborder=\"0\" allow=\"autoplay; fullscreen; picture-in-picture; clipboard-write\"><\/iframe><\/p>\n<p>&nbsp;<\/p>\n<p><iframe loading=\"lazy\" title=\"Tim has a Wobbly\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/k0NloZfdnHE?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>Thanks to John Edmark and Thingiverse users <a href=\"http:\/\/www.thingiverse.com\/thing:1579237\" target=\"_blank\" rel=\"noopener noreferrer nofollow\">nimaid<\/a> and gzumwalt.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Get your creativity rolling with this simple DIY laser cut project<\/p>\n<p>Watching things wobble has something mysterious and mesmerising&nbsp;about it, and when you add in the precision of a laser cutter, the results are mathematically sublime.
