Digital Art

If you are looking for some great digital art to use as desktop wallpaper, I highly recommend Digital Blasphemy. There are a lot of very nice images. (For Linux only) I wrote a little Perl script to change the background image and then used a CRON script to run it every 5 minutes. The script it below:


use File::stat;

$bg_files_dir = "/home/blain/MyDocs/backgrounds";

opendir(DIRHANDLE, $bg_files_dir) or die "couldn't open /usr/bin : $!";
while ( defined ($filename = readdir(DIRHANDLE)) ) {
    push @files, $filename;

$r_file = $files[rand @files];

$inode = stat("$bg_files_dir/$r_file")        
                 or die "Couldn't stat $bg_files_dir/$r_file : $!";

$size = $inode->size;
$mode = "centered";
if($size < 300000) { $mode = "stretched"; }

system("gconftool-2 -t str --set ".
."/desktop/gnome/background/picture_filename $bg_files_dir/$r_file");
system("gconftool-2 -t str --set ".
."/desktop/gnome/background/picture_options \"$mode\"");
