@marmil thanks! Yeah, and I’m terrible, need more practice with the micro. I’m a little better with my 5" quad: https://www.youtube.com/watch?v=LdTTsv8jnVw
As I know - in time they will become more and more unsynched. You may do a “hack”: reset them! ))
For example, always play NEXT animation at start and reset after each animation ))
asm volatile(“jmp 0x00”);
If you will animate starting point for fire - that would look great!
I have no ready-to-use code, but this may be helps

It is by russian, see Lecture6 at the middle of page (look for void shiftk(int *a, int n, int k); )
Thanks for the tip! I’m not really concerned about keeping them synched, for now at least.
Yeah, I need to just get them XY mapped, then I can run all sorts of fun patterns. Shouldn’t take long, I’ll try to get that done today. 
" I don’t really care about keeping them synched."
I’m understand, but if there is simple way to make this - why not ))
If you play 20-30 mins, unsynched animations would annoy you. Just because your lab is genius LOL!!! And unsynched - is not perfect!
Is a joke 
Nice diffuser - PVC film for stretch ceiling. I have try translucent - is works well!
OK, so, lessons learned: my gates were too small. MultiGP Tiny Whoop Class regulation gate size is 19"x19". My flanges suck as stable feet, kept getting knocked over. Next time I’ll screw them down to 2x4’s. Other than that, they seemed pretty well liked. I got a decent fire pattern working, will share video and code soon.
Oh, and 19"x19" is almost 2 meters in circumference. I had some 2m strips, so I made one:missing/deleted image from Google+
Well I guess if you keep practicing with your smaller non-regulation sized gates it will be cake when you have to go race through the regulation ones. :]

@Jason_Coon - Wow! Looks great! Don’t forget to run the water (blue) version of Fire2012with Palette.
You might want to consider playing more with the cooling and sparking variables to get some of the yellow fire near the bottom at times. See the following sketch where I put cooling and sparking as variables when you call the Fire2012with Palette function:
Finally, have you tried making round PEX pipe versions, i.e. rings, of your gates. You could sell them as Christmas RGB LED wreaths which would be easy to hang in a window or on a door.
@Ken_White thanks! Definitely, water is the very next pattern in the list.
Yeah, it looks much better in person. It’s actually white just in the bottom center, then spreads to yellow, then orange, red, etc. You can kind of see it in the reflection off my white desk top. I can’t get my phone camera to reduce exposure any more to keep it from getting blown out.
A round one is next on my todo list. At the race they had square, round, and even octogon gates, all made out of different colors of 1/2" PEX pipe (white, red, blue). They just had cheap coin cell powered white LEDs inside.

@Jason_Coon - Magnificent!! Far Out!! I love Jason’s Ring of Fire! Great job of video taping Jason’s Ring of Fire so that you can see the full fire effect.
@Jason_Coon - Could you please repost your awesome Jason’s Ring of Fire video in a new thread. I am sure many would like to see it but they will miss it because you cannot see the video when you scroll down this web page.
Also, did you use a PEX pipe cutter to cut the PEX pipe? If so, what one did you use? If not, how did you cut the PEX pipe?
@Ken_White thanks! Sure, will do.
I used a ratcheting PVC pipe cutter. They’re awesome, cut through PVC and PEX like butter: https://www.homedepot.com/p/Husky-1-1-4-in-Ratcheting-PVC-Cutter-16PL0101-1/304217581
it would be cool to add some sensors to the inside and outside of the rings, so if they go through the loop it goes green but if they miss it goes red
