noeGNUd is a highly flexible user interface for NetHack and SLASH'EM. It supports ASCII mode, multiple 2D tilesets and hardware-accelerated, partially 3D graphics. It was developed with cross-platform flexibility (especially for flavors of Linux). Binaries for Windows are also available. Since NetHack is a fundamentally two dimensional game, the 3D graphics are actually just the 2D tiles rendered as textures in a 3D world made by extruding the walls upwards.
