+Animations
+==========
+
+Right now it's all a mess. There is a sketch of an api proposal to be
+used by some kind of animation strategy and not much more.
+
+In the main I'm experimenting with cover flow animations. I think one
+"pretty" way of doing cover flow is to align the slides along (tangent
+to, seen from above) a function like the following (gnuplot).
+
+unset parametric
+plot [-500:500]  +1/((sqrt(sqrt(-x)))+1), +1/((sqrt(sqrt(x)))+1/1)
+
+while the distance from the center of the scene should be
+
+set parametric
+plot sqrt(t),0 with linespoints
