Pros:
Based on the animated Batman series, here's a simple but very coherent theme package to put your desktop in Arkham Asylum. Set to run directly from the root of the themes directory, this one contains an 800x600 bitmap wallpaper image, 11 sound files, 4 very good cutout type desktop icons, 12 standard cursors, 2 new animated cursors, and a theme file with a fitting color scheme. All theme parts are named coherently for easy maintenance within the themes directory. An Arkham Asylum Readme.txt file with installation instructions is also included.

Cons:
Mono sound files, several standard cursors and no extra theme parts are available, like system logo screens, web view images or a screen saver.

Overall:
It could be better but considering the small size, it's definitely worth the quick download.
