A paper has recently been published on the Journal of Computational Chemistry that describes the main features of CRYSPLOT.
CRYSPLOT is a publicly accessible web-based tool (http://crysplot.crystalsolutions.eu) to visualize physico-chemical properties of periodic systems (i.e. crystals, surfaces and polymers) as computed with the CRYSTAL code. It has been designed as a very intuitive graphical tool, a low entry-level interface, to all types of users, from beginners to experts, and purposes, from education to research.
