A remix with a single sprite and 100% pen instead of five sprites + pen. Press space to start drawing the moon path. Press space again to delete it.
I noticed that the path of the moon was somewhat delayed (the earth isn't in its center) in the original project, so I figured I'd make a single-sprite version with full control over the execution order to fix that. (I also got rid of the earth path since I don't think it added much.) The result looks good, but I had to use almost twice as many code blocks to make it work. The original project: 5 sprites 45 blocks 0 variables 0 lists This remix: 1 sprite 82 blocks 4 variables 2 lists UPDATE: I added variables to display day, month and year, so it now uses 7 variables and 100 code blocks.
