> When my daughter is old enough

Fwiw, I've done a pinch-nail-hand-arms 1-10-100-1000 mm "body as size reference" a couple of times around 5ish. And a 1000x "micro view" "pinch is zoomed to arms size" "it's like a scale model or doll playset - everything zoomed together" world of "bacteria sprinkles, red blood cell candies (M&M minis or concave Smarties minis or Sweetarts - there's lots of cell candy analogs), hair poles, salt/sugar boxes". Stories of sitting on a grain of salt and eating... etc; pet eyelash mites. No idea if it actually worked.

I did some user-test videos, now only on archive.org.[1] Hmm... the "Arms, hands" video there now doesn't seem to play inline? - but does wget'ed and browsered. :/

Hey that's cool! I like that idea
