Here's a video preview of SIGGRAPH 2009 technical papers,via davidstripinis. Some of these selections were shown in full in the recent AEP post Seam carving, cloning, & cutouts. To see more, you can check out the impressive list of 90 or more SIGGRAPH 2009 papers on the web by Ke-Sen Huang.
BTW, SIGGRAPH 2009 is hosting an Information Aesthetics Showcase "in recognition of the increasingly prominent role that information visualization and data graphics are assuming in our digitally mediated culture." For background, see AEP's Is Information Visualization the Next Frontier for Design?
