You can use regular seed pixels to do a serpentine matrix. The cons of that approach are:

1. You must skip a pixel every row and use a ledmap or live with unequal spacing (5cm pitch vertically and 3.6cm horizontally.
2. It requires infrastructure to and bottom. This makes it a bit harder to assemble, move and store.
3. Unintuitively, it takes longer and is a more difficult build. The reason is all the power injection into the very confined space you’ll need to do.

I did a tutorial on building that style of matrix a while back. [Building a Large LED Matrix (How To)](https://wled.discourse.group/t/building-a-large-led-matrix-how-to/7516)
