Cool use of densityMap and contMap (& in the same figure!)

I just learned of this recent article by Ryan Ellingson et al. which makes very neat use of the phytools functions densityMap and contMap for plotting a posterior density from stochastic mapping on a tree, and for mapping a continuous character on the tree (respectively). See Revell (2013) for more details. Below is a reproduction of their figure. On the left is a posterior density from stochastic mapping of 'benthic' vs. 'infaunal' habit; whereas on the right is a projection of the observed or reconstructed values of a continuous character, relative eye size. For more details see the original article, Ellingson et al. (2013).

**Disclaimer: neither densityMap nor contMap can be used (directly) to add tiny line images of fishes to your tree!
