I created a theme for blender a while ago because i thought the first one was a bit boring, and strangely enough it made me very annoyed for some reason and i then lost my ‘creative touch’ and never managed to make anything good.
anyway this theme is called Autumn :
the .blend : autumn_theme.blend
if anyone else wants to put their homemade themes here please do so 
(to use thes open the .blend and when it opens you can change the default setting if you want, when done press :Ctrl - U, and press ok)
(mods: if this is in wrong place please move )
(also please tell me if this works, because im not sure if it does)
