I know we had a thread like this a while back on 8bc, but it died fairly soon because somebody dropped the ball.
Here's my proposed reorganization for the rules:
1. The challenge passes from the last person who made a picture to the next person. IE, if you were the last person to complete a challenge you get to pick the next person/topic/restrictions.
2. You must pick from someone who has expressed interest in being picked. Preferably in the order requested in this thread.
3. Upon completing the challenge, post the picture here.
4. You have 48 hours from when you see you've been challenged to get it done.
5. When you challenge someone, you MUST put out a public post here, as well as a PM just in case he doesn't see this thread.
6. If the person being challenged takes more than 24 hours to acknowledge that he's seen the challenge, the challenger can pick another and/or change the type of challenge.NEW RULE: You can't get picked to do another challenge unless there is nobody waiting to do one.
Current challenger: Russolo
Challenge: Pixel a 320x200 size image of whatever you want, in 1 bit color. You get to pick your two colors you want to use, but it's 1 bit, so one color is "on" and the other one is "off."
Cool, glad this is happening! Do you have plans to host the results somewhere? I'd suggest downloading all of them yourself and then linking to Photobucket.com or whatever in the first post along with the text of the challenge like I did on 8bc. That way nothing gets lost.
