Works ok, read the (cryptic) installation directions!
October 3, 2015
Pros
As far as I know, this is the only program that will randomly take pictures from a whole directory tree,build an on-screen collage in the wallpaper area, and repeat that every few minutes.
Cons
The only instructions, in the readme file, are a bit cryptic, and you will need to experiment. If you don't follow the installations instructions (which are non-standard), it will do nothing. For Windows 7, especially on very-many-pixel screens: once Thetawall.exe is in the top pictures directory, you may want to set the file's Properties -- Compatibility for all users to "Disable display scaling on high DPI settings" and "Run as Administrator". The program was last updated in 2009, and the controls are pretty limited.
Summary
If you are tired of the limitations of Windows's default wallpaper changer, try Thetawall. Read the readme file and install as directed. Updated on Oct 3, 2015Create a shortcut & put it in the startup folder to have it start whenever Windows starts.
Does not work in Windows 7?!

Pros
Absolutely none
Cons
Didn't appear to execute or do anything? I hope it's a polymorphic virus that brings on the apocalypse!
