I got even closer with 4.992. In case you didn't notice, the icon for this is the same as the current icon for flipclock. I figured this is a placeholder since this is still really early.
I like the idea of different germ poses based on how close you are. Is the goal to get as close to 5 (above or below) or is like 'The Price is Right' where you have to get as close as possible without going over.
One cool thing I thought of when I read 'germ poses' was to take a snapshot using the n810's camera right after the score is displayed. Get a reaction shot image. Using a low res photo like in liqBase would help with speed and to not crash the tablet.
