+Foreground or Background
+========
+
+Description
+-----------
+This patch combines the features of blur-pixelated-screen and dwmlogo; it changes the background of slock to a blurred or pixelated version of your current desktop and the foreground of slock to a dwm logo that changes color based on the state.
+
+Notes
+-----
+The size of the logo is configurable with `logosize` in the `config.h`.
+
+This patch is not limited by the dwm logo.
+By changing the `rectangles` variable in `config.h` you can create any figure based on rectangles.
+
+Define either `BLUR` (default) or `PIXELATION` to set which type of masking you want applied to the screen. You can also change the blur radius and pixel size with `blurRadius` and `pixelSize`, respectively.
+
+With the `dpms` patch there is a conflict in the `main` function.
+This is easly fixed by editing the `main` function in `slock.c`
+so it looks like this, for it to work properly:
+
+ main(int argc, char **argv){
+ ...
+ XFreeGC(dpy, locks[s]->gc);
+ }
+
+ /* reset DPMS values to inital ones */
+ DPMSSetTimeouts(dpy, standby, suspend, off);
+ XSync(dpy, 0);
+ XCloseDisplay(dpy);
+
+ return 0;
+ }
+
