Keyhole's EarthViewer3D harnesses the power of NVIDIA GPUs. Fusing high-resolution satellite and aerial imagery, elevation data, GPS coordinates, and overlay information about cities and businesses, EarthViewer3D delivers a streaming, 3D map of the entire globe to PCs powered with NVIDIA GPUs.

Very cool. I wish they offered bulk pre-caching of the imagery, rather than streaming it on demand.
