Just press the green flag. This is just a preview of what's hopefully coming soon. The finished thing will have clouds and use the season to figure out the weather (and associate the precipitation with clouds) (and have shading on the mountains to go w/ the bg) Anyways, what it does do is change the background based on the time of day and possibly give you random rain or snow. You might want to press the flag multiple times, each time is different. I've been doing so much on this account and I haven't been doing much programming on Scratch and it's kinda fun to be doing something with both. :)
