Rings are so nice and can be used in multiple ways , if you just want to use it as matrix in 2D then there is examples here in discord using ledmaps Discord , as you see in the gif that would mean you can use 2D effects like text or use pictures , stream video …etc
I personally like to use rings both in 2D and in 1D as if you have time to experiment you could do a lot in 1D with segments
If you want more examples then might be join discord and look in the 2d channel
