Cindy and I got adventurous this weekend and made a fruit tart:

Here's the recipe we used, from JoyOfBaking.com. It does take a while to make (at least the first time), but comes out very good. Do let the filling sit overnight as it gets better the next day. And I used vanilla extract instead of vanilla bean.

New in this edition: C-spheres

In general, a C-sphere is a surface in the boundary of hyperbolic space that is topologically a sphere and is foliated by chains (C-circles). One way to specify a C-circle is to give a path in homogeneous coordinates that provides vectors that are normal to the chains. The left picture is given by the path

$\gamma(t) = ( -t^3, \sqrt{2}, t)$

The points corresponding to $t=\pm1$ are $(\pm 1, 0, 0)$ . Taking them to $(0,0,\pm 1)$ produces the picture on the right.

Note: the notebook ComplexHyperbolic0.5 did not draw correct C-spheres, so it's no longer available. The code for the images above will be in CH0.6.
