This is a pack of miscellaneous 3D models and textures from a planned game called Grindstone.
Not everything is textured, and some of the stuff that is textured isn't textured very well. There is no particular theme, although the props were meant for a modern office environment.
There's also a Sci-Fi vehicle in there...honestly, you're better off downloading it (it's free!) and see what there is.
Released in the public domain. You can use these however you want with no attribution required.
