type in your token here:
pick colors from the picker below and click on the canvas to add pixels. you can undo the pixels you added by clicking the button below. once you are satisfied with your work (and your token has been validated) you can submit the pixels you added. you should try to use up all the pixels you can because you will not be able to reuse the token. you can split your token into two, but note that smaller tokens give you fewer pixels in total. you can also combine two tokens into one (and get bonus pixels)
