Ti 83 Based Drawing?

Those of you who used to draw on Ti 83's might know where I'm coming from. I love to draw pixel art on the 83+, but I wish that the pixels had color. I like to see an app that uses a D-Pad and an "Enter" button to place the pixel in the desired location, just like on a 83. The option for color and the ability to save current work so that I could go back to drawing later.
