Been looking for months now, but I just haven't found a PS3 theme that beats the original wavy lines one that comes with the console. Well, I hadn't. Have now.
m0dus & orioto, a couple of kids on GAF, have whipped up this homemade Gunstar Heroes theme. All HD, all hand-drawn, like the Gunstar Heroes: Rearmed that only exists in your dreams.
It's even got custom icons! Perfect.
