Hi!
I have been working hard on this theme for Android phones. I'm aiming for that white, clean, minimalist Aperture Science feel.
If you have Android phone you should totally try it. It requires Go Launcher EX as home app, so make sure you install it first.
Any feedback helps

Oh, it looks really sweet, too bad Go Launcher EX drains my battery so much :S
But as soon as I re-charge my phone again I'll definitively will give it a go.
