or for that matter:
function d(a,b,c){c=a.style.opacity=+!c;setTimeout(d,b||500,a,b,c)}(67 bytes)
or even:
function d(a,b,c){setTimeout(d,b||500,a,b,a.style.opacity=+!c)}(63 bytes, assuming you're okay with losing old browsers)
Interesting.
Supporting the current and previous version of each major browser would be nice. No ?
IE8, does not support setTimeout(function,delay,arg1,arg2,...), so... 68 ?
i'm happy with 68 (unless we want to dial down the default to 99 for 67).
Oh dear, it's amazing.
And finally i make bitwise trick useful.
function(a,b){setInterval(function(){a.style.opacity^=1},b||500)}
(65 bytes)
whoa, nice! i think that's the first useful XOR assignment i've ever seen here.
I think that's it. There's not much code left to optimize here.
Sorry for the b=...=b?0:1 in my previous comment. That was lazy. It was obvious there was room for improvements.
