Probably I'll eventually get sick of this style (previously: [1], [2], [3], [4]), but in the mean time I'm having fun.
Here's the source code:
Manipulate[
Graphics[{FaceForm[None],
EdgeForm[Directive[RGBColor["#00FFF5"], Thickness[.005]]],
Table[Module[{?, xpos, ypos},
{xpos, ypos} = {Sqrt[3] x + ((-1)^y - 1) Sqrt[3]/4 + Sqrt[3]/2 i, 3/2 y + 1/2 i};
? = ?/3 (Haversine[Mod[#, ?]] + Floor[#/?]) &[t - ?/ Sqrt[417] Norm[{xpos, ypos}]];
Polygon[
Table[{Cos[? + ?], Sin[? + ?]} + {xpos, ypos},
{?, ?/6, 11 ?/6, ?/3}]]],
{x, -9, 8}, {y, -10, 10}, {i, 0, 1}]},
ImageSize -> 540, PlotRange -> 15,
Background -> RGBColor["#222831"]], {t, 0, ?}]
