I used a hack to make the key vars: http://scratch.mit.edu/projects/SSBBM/1032265 Trail blocks: Trail block are like pen and stamp, but they go away. I think that we should have these blocks: Trail on Trail off Set trail time to [] Change trail time to [] Set trail to pen Set trail to stamp Trail on and off are like pen up and down. Setting the trail to pen will do what the pen does except it will go away. Setting the trail to stamp will make it stamp, not pen. (If you have confuion about this let me know and I will post a project.)
