Kol, random, open-ended game in which you can change 1 pixel per turn. Borders cannot be modified. Maybe you'll try to make the whole thing a single color, or build a rainbow, or 'war'. Don't double post unless a day has passed with no one going (we can vote on this if it's an issue).
Adding 1 pixel shouldn't take long, but feel free to post taken to reserve your turn for 5 minutes
