I took this picture last year when I was reviewing a pixel art app for Android. It was pretty good, although it was lacking in the colour pallet options (As you can tell by the shading!)
If you are interested in such things, you can find the app here on Amazon.
I've tried a few of these for the iPhone, definitely handy if you only have a phone to work with and your away from the computer
I totally agree. Nothing better than satisfying the pixel art cravings by being able to play about when not at the PC :)
oh this is kinda cool app :)
