The table recognises some mouse events
Fixed positioning of messages regarding candidates
Trying to improve the Hodge diamond

I'd like to show the h^{i,j}'s in a meaningful way.
All the numerical invariants from Wikipedia

They are not dynamic yet, but the layout seems to be okay.
Two column layout

Ideally speaking I'd like to have to following:

1) when the screen is sufficiently wide: two columns of fieldsets

2) when the field is not big enough (i.e. <= +/- 1200px at the moment) go to 1 column

3) have the svg element as position: fixed so it is always in view, even when scrolling down on small screens to see the invariants

I now realise that with a bit of JS hacking this is not too hard, but I hope there is a CSS solution (I'm afraid that the position: fixed might ruin this hope though)
Improved layout of the table and added axes (!)
Improved layout

Not the ideal solution (doesn't degrade nicely) but it looks good and is workable on lower resolutions.
Fixes to numerical invariants

Still static though...
