Sounds like a trivial perl script to me.

#!/usr/bin/env perl

# Yes, I know this is bad/unsafe for odd filenames.
my @files=`ls -1 ~/Pictures/Best/*g`;

# pick a randome file
my $bg = $files[rand @files];

`env DISPLAY=:0 /usr/bin/feh --bg-scale $bg` ;

There is probably a bash way too.  I run this from crontab every 30 min to
change the desktop background. You could easily wrap the important parts in a
while/sleep loop.

What does the kernel care about rotation? I'm confused and don't understand.
