From the developer:
ET Surface is a set of tools for ArcGIS that enable the users to create surfaces and perform surface analysis without the need of 3D or Spatial Analyst extensions. The only requirement is an ArcGIS license (ArcView, ArcEditor or ArcInfo).
ET Surface 2.0 introduces ET TerrainViewer which allows 3D visualization of surfaces (PolygonZ TINs and Rasters) as well as features stored in shapefiles.
