@marmak3261 that is freaking awesome! That so helps me. Also opens up a ton of new possibilities. Thanks!
@marmak3261 i tried the instructable. It works great right up to creating the SVG. The part to download the SVG doesnāt seem to work for me. Any one who knows Javascript and HTML have an opinion?
Actually just tried this in Explorer rather then Chrome. It doesnāt download, but I can right click and save. So thatās fine by me 
I upgraded to Windows 10 today so didnāt take the time to load the script. Will work on it and see. Glad you got it working. One of the things that I noticed first in the gift shops were laser earings and I have quite a few nieces and sisters-in-law and other worthy earing wearers that Iād love to make bespoke earings for. Iāve been fascinated by computer generated art for a long time and when I taught elementary technology we used Scratch to make lots of pretty spirograph stuff that they could then color inbetween. Never thought of it being useful, but now with a Glowforge, it will be.

I got a little a head with it. Canāt get the download part to work , but in explorer and not chrome I can right click and save as SVG. Also I cannot for the life of me figure out how to add a line to an existing path. I think Iāll just make a variable , have a string in it , and make a loop that adds to the string each segment . then feed the variable that has a string of the full path into the SVG path. Iāll try tonight.
Work always in the way of goofing around .
This is cooler than words can describe. Canāt wait to make one, too!
Also want to put this link. Now that I have the JavaScript base code I do want to play and be inspired by these doodles.
Oh cool. Last two days at work have been killer. But tomorrow its just me and the couch. So I hope by Sunday , maybe have something to show.
Wouldnāt mind trying to put something together for the community. Or have a ābest equationā contest

Ok so quick update, Iām heading out but just got something working. Iāll go into more detail later.
Javascript and SVG libraries are a little above my level of tinkering. After spending half a day yesterday pound away, I got a something. I think my major problem is the coordinate system. I need to figure out how to shift it from being 0,0 in top left to being centre, centre, 0,0. Preferably with top right side being positive, positive. I plan to get back to that later.
I use to know Excel and VBA so I resorted to that. The process I have at the moment is:
1 - VBA macro to generate table of points(was able to reduce my level of accuracy and still keep my lines)
2 - same macro(or manually) creates a XY scatter graph with lines
3 - macro then turns off axes, legend, etc
4 - save graph as PDF
5 - open in Inkscape, fiddle and/or resize if need be, save as SVG
I tried to just save the points as CSV and figure a way to convert to SVG, but found nothing easy. Also with excel, I found it easy to make all my variables easy to change to get different results. Next step is to figure away to do different equations. Batman equation maybe?
I am sure OpenOffice could do the same. I just prefer Excel. Also with Excel I can see my numbers and understand whatās going on. With Javascript, I was stuck writing a word document and praying. I would really like to do a Javascript version. Anyone more familiar with that stuff, please contact. Would love to try to create a something.
Cheers all
If you havenāt tried Scratch from MIT you should give it a look. Many of the sample programs are easy to tweak to get interesting loops and whirls. They really are easy to program. The images can be saved as a .png and worked with after that. here are some parametric examples. iOS need not apply at the moment because itās Flash dependent but that will change soon. Iāll highlight specific ones when I move to a Flash friendly device later on.
Iād try Processing or Python, which have more extensive libraries and are more powerful in many ways than scratch. I realize programming languages are like religionsā¦
Learning curve on Scratch is pretty small. I use that for teaching coding basics for elementary students. So for a math novice that hasnāt made it to sine and cosine, regular polygons can give some cool things. Once the students know a polygonās angles add up to 360, there are simple routines that generate them. Such as this one. Just changing a few of the numbers can do some neat geometry.
Most of the school around here are using Processing for teaching. Google has been pushing that locally; again there is no right language, but the one you successfully build your program in.
Hereās a 5 mins example of this in Fusion 360. (Very quick, thrown together example)
Basically created one tangent curve then use that to create a pattern. Then made a offset of that pattern every 10mm.

The language choice is a deep subject. Itās the baby duck syndrome for me. However as @henryhbk pointed out, some are more novice friendly. This appeared at Make magazine today and seems custom made for those just getting started in programming and design. http://makezine.com/2015/11/09/learn-to-make-interactive-graphics-with-updated-getting-started-with-processing/

@marmak3261 For novices they (all these āmagicalā languages) are great as you can get started quickly and get the general idea of how to program, and are great for quick-and-drity apps like this case. As an enterprise developer, who cut his teeth on IBM 360 and PDP-8 assemblers, Iām not a huge fan of āmagicā since I now develop mission critical healthcare applications, where bugs can actually hurt people. I prefer strictly typed languages without any magic (ruby-on-rails I am staring at you!) since I donāt want some library call ādeciding what I meantā if I make a mistake (mostly work in Java).
@henryhbk well it would be nice to be able to code from the ground up and know all the tricks, I spend 40 plus hours a week on a saw and workbench. I donāt have time or energy to learn the very depths of coding when all I need is a pretty picture generated. So ārailsā , fences, barbed wire , frameworks or what ever, Iām more then happy to be lead by the nose. After all worse comes to worse my programs canāt kill anyone(well I assume , we will see how the beta testers do).

@karaelena cool! I do something slightly different. I havenāt thought about doing it with a flowerish type pattern.
