Hmmm it's always interesting to look at these things, I am considering the =
Atiny series for... tiny stuff. So tiny in fact milligrams are important.  =
As for inhaling, you have a point, these could become chocking hazards for =
mice! (Call the press!)  There are applications for extremely small package=
s like this in any case (in my case a pager motor speed controller) and pic=
o sized servo control system.  The big problem is converting a PWM input in=
to an analog control output. :D

Real application, really crazy, (but fun) stuff. There are numerous applica=
tions for these, as in swallow-able medical devices, LED dimmer control sys=
tems, Christmas tree lights. You have a myriad of uses in under a second ri=
ght there. The developer is the limiting factor for uses for such tiny devi=
ces. Golf ball implanted strike count for golf (IE I only hit it 4 times! T=
he golf ball states 5 hmmm).
