That is so cool. I like the little sperm-like individual.

Heh... thats not a sperm :) its a microbe. Sperms aren't capsule shaped (i had this conversation with the scientists already ;P) Whats really cool, that you don't get to see in this animation, is how it "tumbles". Those flagellas wrap together and form one spiral, that pushes it forward... when it wants to turn around, or change directions, it flays all the flagella out (like it is in this animation) and tumbles around until it rights itself, then wraps all its flagella together again to move forward. :)
