I created this with the intention of making a black and white avatar.
Eventually, it just ended becoming anti aliasing practice. I don't think I have it quite yet.
The under aliased ones I did looked pretty cool, but now it's probably over AA'd.
It's pretty basic, I know.. and it only took me about 10 minutes.
I used the 5 bit monotone palette (16 tones) I made, but I definitely didn't use all the tones.
Microsoft Paint.
