First line as "a=b=>128*(S(t*b)+1)" brings this to 140.
u/andy

Thanks, that's right. Didn't even realize i was over 140 :)
u/lionleaf

Are you seeing over 140 characters? On chrome it says 140/140 at least.
u/andy

weird, yesterday it said 143.
u/michelinux

It's probably because on Windows the new line takes 2 characters ('\n\r'). Use ';' instead of new line and you should have a more consistent behaviour.
u/andy

still weird, i don't have any windows machines.
u/SpecialAgent

the simplicity of that zoom blows my mind, great work!

u/rodrigo.siqueira

Thanks @joeytwiddle for the golf trick. i*(t&1) also works and it's even shorter. And I found that t%4>2?... can be converted to t&2?... It works as a counter to change the function each 2 seconds.
u/yonatan

Also, since T and S take the same arguments (t%4>2?T(b+t):S(b+t)) can be (t&2?T:S)(b+t)
