In the past, I had asked if there was an easy way to get all 3rd party patterns easily instead of a painful one by one load of dozens of them. Thankfully @wizard partially fixed this by making it much easier to directly load patterns from a running PB and even made nice categories so you can find all the 2D patterns trivially. That really helped, thank you.
Still, it took around 2H to try them all and make a playlist with my favorite ones, so to save someone else the work, I just backed up my entire device and I’m sharing the archive here:
I realize those backups are not really meant to be shared with others and that you’ll have to reset the wifi as well as the hostname and a couple of settings like resolution, but once you do, you’ll get all the patterns already loaded and ready to run. Hope that saves you 2H and you enjoy them 
Also, I made a video:
And I wrote a blog post about my experience with that many pixels in a single chain and ultimately the multi device support not working for me due to lack of time sync between devices, not counting the fairly puzzling config to map where each device is in the combined framebuffer.
I was hoping to increase my framerate by 2x or 3x with 2 or 3 picos, but without timesync, that’s not possible, so I’m making do with an average 5fps or so (with a total 10fps on the neopixel wire output)
Hope this helps
