I've been slowly working on a 3D file manager that's operated like a first-person shooter. I was originally inspired to think along these lines by DOOM for sysadmins, and other people have tried similar things (Brutal File Manager, Virtuadesk) but nothing I've seen quite matches what I wanted to try. So, I started to develop it.
I'd suggest reading the design document to help understand the screenshots below. Click on the thumbnails for larger images.
|An early effort.|
|A symlink - note the translucency.|
|A full room. Doors into subdirectories on the far wall, various files in the foreground.|
|A better view of the subdirectories.|
|Close up on a text file.|
|A makefile in the foreground, a shell script behind.|
|Images textured with a thumbnail of the image.|
|A preliminary HUD; putting the cursor on an object displays information about it.|
|The door to a parent directory from the /tmp directory. Note the different color and texture, indicating that it has different permissions and is on a different filesystem. The HUD indicates the filesystem type.|
|The HUD on a different file.|
|Subdirectories in the /tmp dir.|
