Fixed.

I've fixed that.

That's actually a good advice. Does a separate, "static" screenshot also work?

Sure, that would work just as well. Plus, then you get to pick a "good" placement instead of making the user try to find one.

Ok. I will add them tomorrow. Also I will fix the first animation (b doesn't grow there as it should).

Thanks for spotting this. I've mixed two ideas. Need to comeback to it. The smaller circle has to increase its size as b grows. As it is now it works because o triangle degeneration.

Blog looks promising. Is there a RSS feed associated with it?

My grandfather was a math teacher, and "Gazeta Matematica" was "his life".

Not a garden but I also curtate links that I find interesting here:

And maintain an active blogroll with blogs I follow:

Fun fact, in the book Life Of Pi, the kid stays exactly 227 days on the boat with the tiger.
