    very cool. like the morphing / moving dots / lines #cube #3d
  • u/tomxor
    Very neat. The migration of the points gives it quite an etherial look.
  • u/aleamb

    u/vain It is the combination of rotations, scaling and translations (setTransform) and transparent color (.07 opacity). I remix and play with parameters and all stems from u/pavel 's Underwater cavern: https://www.dwitter.net/d/18597 My previous dweets are also remix of it. The math formulas (sin and cos) are not the main thing, they just create some almost random numbers with cyclic properties. I can not predict the result only looking to the formulas. I remix and explore combinations and post when I find interessting results.
