I participated in Mini-Comics Day 2012.
Here's a link to see what was made in Minneapolis that day:
Mini-Comic Day was from 11am-5pm in Minneapolis. Each creator had that time to write, draw, and copy a Mini-Comic. It was a lot to get done in one day but I was able to get something finished.
My Mini-Comic folded into a finger football. I was pleased enough with the idea so I think I'll make a less rushed version of it.
