High quality 3D graphics - the Spotlight module
The potential for making stunning and beautiful graphics with THREE.JS is high. Check out their examples pages for inspiration, and keep in mind that anything there can be replicated within Evince.
Notably, the post-processing options in THREE.JS are interesting from a "get-that-cover"-perspective (keywords: bloom, dof, sao, raytracing, mm).
I've made a prototype for a viewer called SpotlightView, where certain post-processing options are active. It currently works with BubbleBox, but can easily be extended or customized for another input format.
This module will likely support the HSP-molecule object in the very near future.
