GigaVoxels at Siggraph

Cyril Crassin will be giving a talk at Siggraph 2009 on the subject of voxel raycasting and he has published a new short paper:

Some screens of raycasted voxel scenes with the GigaVoxel technique here

I also found an interesting blog (via Timothy Farrar's blog) called EnterTheSingularity, which features a very interesting and in-depth post about the "perceived" latency of cloud gaming services:
