# Mathematica ASCII I really like ASCII art, so I add another very different answer - especially so it's so short in Mathematica: Column[Table[Row[RandomChoice[{"+", ".", "*", "~", "^", "o"}, k]], {k, 1, 35, 2}], Alignment -> Center] ![enter image description here][1] And now with a bit more sophistication a scalable dynamic ASCII tree. Watch closely - the tree is also changing - snow sticks to branches then falls ;-) DynamicModule[{atoms, tree, pos, snow, p = .8, sz = 15}, atoms = { Style["+", White], Style["*", White], Style["o", White], Style[".", Green], Style["~", Green], Style["^", Green], Style["^", Green] }; pos = Flatten[Table[{m, n}, {m, 18}, {n, 2 m - 1}], 1]; tree = Table[RandomChoice[atoms, k], {k, 1, 35, 2}]; snow = Table[ RotateLeft[ArrayPad[{RandomChoice[atoms[[1 ;; 2]]]}, {0, sz}, " "], RandomInteger[sz]], {sz + 1}]; Dynamic[Refresh[ Overlay[{ tree[[Sequence @@ RandomChoice[pos]]] = RandomChoice[atoms]; Column[Row /@ tree, Alignment -> Center, Background -> Black], Grid[ snow = RotateRight[ RotateLeft[#, RandomChoice[{(1 - p)/2, p, (1 - p)/2} -> {-1, 0, 1}]] & /@ snow , {1, 0}]] }, Alignment -> Center] , UpdateInterval -> 0, TrackedSymbols -> {}] ] ] ![enter image description here][2] [1]: https://i.sstatic.net/HBCvn.png [2]: https://i.sstatic.net/ArhPo.gif
