This is a cool optical illusion style design that’s been done quite a lot. I tried to make it a bit different by creating two interlocking lines on my feature nails. The contrast between holographic and creme polishes makes it stand out too.

Spacing is really important with this design, you don’t want to leave more than a single dot’s width between the same colour dots or it won’t work when you add the contrasting colour.
