Other interesting things to try -- you can create something to call into to synthesize motion with something like:

  function domove(x,y,a) { moveFlag(me.flag, x, y); setRotate(me.flag, a); emit('motion', {x: x, y: y, id: me.id, c: me.country}); emit('scroll', {id: me.id, angle: a}); };

and then you can do more interesting stuff along the lines of:

  a=0; function f () { a += 5; domove(a, Math.sin(a / 50) * 100 + 200, a); if (a < 1000) setTimeout(f, 20); } setTimeout(f, 10);

I hope I'm not breaking any rules replying to own post (tried to edit but wouldn't let me)

better tree:

    test("\n:sparkles::sparkles:    :star2:  :sparkles:\n        :christmas_tree:\n  :sparkles:   :christmas_tree::christmas_tree:    :sparkles: \n:sparkles:    :christmas_tree::red_circle::christmas_tree:  :sparkles:\n     :christmas_tree::ribbon::red_circle::christmas_tree:   :sparkles:\n    :christmas_tree::christmas_tree::christmas_tree::ribbon::christmas_tree:\n :sparkles:  :christmas_tree::red_circle::christmas_tree::christmas_tree:    :sparkles:\n    :christmas_tree::christmas_tree::red_circle::christmas_tree::christmas_tree:\n   :christmas_tree::ribbon::christmas_tree::christmas_tree::red_circle::christmas_tree: :sparkles:\n:sparkles::christmas_tree::red_circle::christmas_tree::ribbon::red_circle::christmas_tree::christmas_tree:\n        :door:")

Can't believe I spent half an hour on Christmas day making an emoji tree
