I've seen a few very interesting BOINC graphics.

The malaria project is one of the most unusual. You can rotate the plane in x y z directions to see your relief map better. How is it shadowed? by the sun and moon whizzing around a planetoid, the rendered field of which you are above. You get sunrises/sets and moonrises/sets. For good measure, some flying mosquitoes are buzzing around for you to swat away. The phases of the moon don't change, but that is an acceptable compromise.

I like Rosetta/Ralph for their vector graphics treatment and dynamic molecule movement, settling in on a low-energy form. One phase shows a line graph. Another phase shows 2 line graphs in x and y direction, and an intersection box.

The rotating celestial sphere in Einstein is educational.

The rotating earth in the continental simulation can show clouds, rain/snow, or pressure. It's a nice way to follow a very long running workunit.

I liked the old docking graphics in grid.org before they stopped doing useful work, because it showed actual renditions of different chemical molecules, either in stick or 3-d form. Can't you get Oxford to come over here, now?
