And bookmarked. I actually never knew that Ouroboros meant anything outside of this game, and now that I know what it means I love it all the more. She talks really fast and her doodling far surpasses mine, bit I fully intend to master this as far as my short attention span allows me.
Edit to respond to Tony's edit: That reference made he math geek inside me smile.
I love that chick's videos so much - partly because I dabble in math myself, but mostly because they're just awesome. 
I just wish she updated more often!

This is what it means to be a tank!
If she's a graduate student, we're lucky she finds time to update at all.
Just as a point of interest, I was watching one of "mathemusician" Vi Hart's math doodle videos, Doodling in Math Class: Snakes + Graphs, and I was struck by one of the finest practical application of Ouroborii that I've ever seen. She even two-ups the City of Heroes "Infiniborous" design...

With a couple of her own designs: Ouroborromean Rings (based on topological Borromean Rings) and a beautiful Möbiaboros.
Anyway, if you're a math geek like me, you'll love seeing something semi-obscure in the game in a context outside of the game. (And you'd do well to voraciously bookmark and watch Vi Hart's videos.
Edit: Watching it again, I just caught her reference at 1:06 to "snakes on a plane..." *groan*...
We've been saving Paragon City for eight and a half years. It's time to do it one more time.
(If you love this game as much as I do, please read that post.)
